GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(392, 544) = 26656
GCD(392, 544) = ( 392 x 544 ) / 26656
= 392 / 544
= 392
Step2:
LCM(8, 674) = 2696
GCD(8, 674) = ( 8 x 674 ) / 2696
= 8 / 674
= 8
Step3:
LCM(2, 720) = 720
GCD(2, 720) = ( 2 x 720 ) / 720
= 2 / 720
= 2
So, Greatest Common Divisor of 392, 544, 674, 720 is 2
