Given numbers are 674, 278, 231, 130
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(674, 278) = 93686
GCD(674, 278) = ( 674 x 278 ) / 93686
= 674 / 278
= 674
Step2:
LCM(2, 231) = 462
GCD(2, 231) = ( 2 x 231 ) / 462
= 2 / 231
= 2
Step3:
LCM(1, 130) = 130
GCD(1, 130) = ( 1 x 130 ) / 130
= 1 / 130
= 1
So, Greatest Common Divisor of 674, 278, 231, 130 is 1
