Because 35 is the lowest number that both 5 and 7 will divide into evenly.
List the multiples of 5 and 7.
5, 10, 15, 20, 25, 30, 35, 40
7, 14, 28, 35, 42
35 is the smallest number that appears on both lists.
The least common multiple (LCM) of 5 and 7 is 35.
lcm(7, 20, 35) = 140 7 = 7 20 = 2^2 x 5 35 = 5 x 7 lcm = 2^2 x 5 x 7 = 140
hcf is 1 and LCM is 35
Factor them. 7 2 x 2 x 5 = 20 5 x 7 = 35 Combine the highest amount of each factor. 2 x 2 x 5 x 7 = 140, the LCM
Least Common Multiple (LCM) for 5 7 is 35.
The LCM is 35.
The LCM of 7 and 5 is 35 because 7 x 5 is 35 and 5 x 7 is 35, so 35 is the LCM
LCM(7, 5) = 35.
The LCM of 5 and 7 is 35. LCM stands for Least Common Multiple, or Lowest Common Multiple.
The LCM is 35. 5 x 7 = 35 7x 5 = 35
The least common multiple (LCM) of 5 and 7 is 35.
lcm(35, 49, 7) = 245 35 = 5 x 7 49 = 7^2 7 = 7 lcm = 5 x 7^2 = 245
45 = 5×9 35 = 5×7 LCM = 5×7×9 = 315
5 5 x 7 = 35 The LCM is 35.
It is: 35
lcm(7, 20, 35) = 140 7 = 7 20 = 2^2 x 5 35 = 5 x 7 lcm = 2^2 x 5 x 7 = 140
2 x 2 x 7 = 28 5 x 7 = 35 2 x 2 x 5 x 7 = 140, the LCM
