WebAll the "2"s are now above each other, as are the "3"s etc. This allows us to match up the prime factors. The highest common factor is found by multiplying all the factors which appear in both lists: So the HCF of 60 and 72 is 2 × 2 × 3 which is 12.. The lowest common multiple is found by multiplying all the factors which appear in either list: So the LCM of … WebHighest Common Factor & Lowest Common Multiple Mark Scheme Working a) Find the lowest common multiple (LCM) of 40 and 56 A = 2 3 x 3 x 5 B = 2 2 x 3 x 5 2 b) Write down the highest common factor (HCF) of A and B. …

WebApr 9, 2024 · Solution For Q.57 If the sum of two numbers is 40 , and the HCF and LCM of these numbers are 8 and 48 , respectively, then find the sum of the reciprocals of the … WebApr 6, 2024 · Since the divisor at this stage is 28, the HCF of 56 and 84 is 28. Notice that 28 = HCF(56,28) = HCF(84,56) . We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma. Step 1: Since 1134 > 28, we apply the division lemma to 1134 and 28, to get. 1134 = 28 x 40 + 14 cow riding in car

WebRefer to the link for details on how to determine the greatest common divisor. Given LCM (a, b), the procedure for finding the LCM using GCF is to divide the product of the numbers a and b by their GCF, i.e. (a × b)/GCF (a,b). When trying to determine the LCM of more than two numbers, for example LCM (a, b, c) find the LCM of a and b where the ...
