Question

can you please let me know what is the answer​

Answer 1

Answer:

$70 = 2 \times 5 \times 7 \\ \\ 140 = 2 \times 2 \times 5 \times 7 \\ \\ 350 = 7 \times 2 \times 5 \times 5 \\ \\ lcm = 2 \times 2 \times 5 \times 5 \times 7 = 700$

Answer 2

Answer:

Using Prime factorisation method,

Lcm of 70, 140, 350

$70 = 2 \times 5 \times 7 \\ 140 = 2 \times 2 \times 5 \times 7 \\ 350 = 2 \times 5 \times 5 \times 7$

LCM,

$2 \times 2 \times 5 \times 5 \times 7$

= 700
