Given numbers are 139, 357, 767, 615
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(139, 357) = 49623
GCD(139, 357) = ( 139 x 357 ) / 49623
= 139 / 357
= 139
Step2:
LCM(1, 767) = 767
GCD(1, 767) = ( 1 x 767 ) / 767
= 1 / 767
= 1
Step3:
LCM(1, 615) = 615
GCD(1, 615) = ( 1 x 615 ) / 615
= 1 / 615
= 1
So, Greatest Common Divisor of 139, 357, 767, 615 is 1
