Answer 2

Answer:

lcm = 7 X 3 X 5 = 105

Step-by-step explanation:

    3 I 21           5 I 35

    7 I 7             7 I 7

       I 1                 I 1

so you should take the left side numbers which are 3, 7, 7,5. these numbers are prime numbers. to find the LCM take the largest number. for example in 21, 3 comes 1 time. but in 35, 3 is not there. so 3 you have to wright one time. but if 3 is there in 35 but comes two times, then you have to wright two times 3. like that it will go. if you didnt understant then just wright LCM as 105.
