Given numbers are 274, 407, 615, 139
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(274, 407) = 111518
GCD(274, 407) = ( 274 x 407 ) / 111518
= 274 / 407
= 274
Step2:
LCM(1, 615) = 615
GCD(1, 615) = ( 1 x 615 ) / 615
= 1 / 615
= 1
Step3:
LCM(1, 139) = 139
GCD(1, 139) = ( 1 x 139 ) / 139
= 1 / 139
= 1
So, Greatest Common Divisor of 274, 407, 615, 139 is 1
