GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(742, 320) = 118720
GCD(742, 320) = ( 742 x 320 ) / 118720
= 742 / 320
= 742
Step2:
LCM(2, 654) = 654
GCD(2, 654) = ( 2 x 654 ) / 654
= 2 / 654
= 2
Step3:
LCM(2, 280) = 280
GCD(2, 280) = ( 2 x 280 ) / 280
= 2 / 280
= 2
So, Greatest Common Divisor of 742, 320, 654, 280 is 2
