Question

I verify that HCF of 10, 15 and 20 is a
factor of LCM of the same numbers​

Answer 1

10 = 2 × 5

15 = 3 × 5

20 = 2 × 2 × 5

H.C.F = 5

L.C.M = 2 × 2 × 3 × 5 = 60

Answer 2

Step-by-step explanation:

10=2×5

15=3×5

20=4×5

LCM=2×5×3×2=60

HCF=5

60=12×5

we see that 5 is factor of 60 therefore HCF of 10,15,20 is a factor of LCM
