GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(278, 368) = 51152
GCD(278, 368) = ( 278 x 368 ) / 51152
= 278 / 368
= 278
Step2:
LCM(2, 812) = 812
GCD(2, 812) = ( 2 x 812 ) / 812
= 2 / 812
= 2
Step3:
LCM(2, 430) = 430
GCD(2, 430) = ( 2 x 430 ) / 430
= 2 / 430
= 2
So, Greatest Common Divisor of 278, 368, 812, 430 is 2
