a)mmc (4,5)

b)mmc (2,3,5)
c)mmc (5,15)
d)mmc ( 4,7,10)
e) mmc (15,20)​

Answer 1

MMC (4,5)

4, 5 | 2

2, 5 | 2

1, 5 | 5

1, 1 | 1

$mmc = {2}^{2} \times 5 = 20$

MMC(2,3,5)

2, 3, 5 | 2

1, 3, 5 | 3

1, 1, 5 | 5

1, 1, 1 | 1

$mmc = 2 \times 3 \times 5 = 30$

MMC (5,15)

5, 15 | 3

5, 5 | 5

1, 1 | 1

$mmc = 3 \times 5 = 15$

MMC(4,7,10)

4, 7, 10 | 2

2, 7, 5 | 2

1, 7, 5 | 5

1, 7, 1 | 7

1, 1, 1 | 1

$mmc = {2}^{2} \times 5 \times 7 = 140$

MMC (15,20)

15, 20 | 2

15, 10 | 2

15, 5 | 3

5, 5 | 5

1, 1 | 1

$mmc = {2}^{2} \times 3 \times 5 = 60$
