GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(642, 492) = 52644
GCD(642, 492) = ( 642 x 492 ) / 52644
= 642 / 492
= 642
Step2:
LCM(6, 800) = 2400
GCD(6, 800) = ( 6 x 800 ) / 2400
= 6 / 800
= 6
Step3:
LCM(2, 796) = 796
GCD(2, 796) = ( 2 x 796 ) / 796
= 2 / 796
= 2
So, Greatest Common Divisor of 642, 492, 800, 796 is 2
