Heya !!
Prime factorisation of 44 = 2 × 2 × 11
Prime factorisation of 420 = 2 × 2 × 5 × 3 × 7
HCF of 44 and 420 = 2 × 2 = 4
We know that,
One number × Other number = HCf × LCM
44 × 420 = 4 × lCM
lCM = ( 44 × 420/4 )
LCM = 4620.

44=2×2×11 and 420=2×2×3×5×7 common 2×2=4 hence 4 will be the hcf again lcm=2×2×3×5×7=980 hence 980 will be the LCM
