Given numbers are 126, 855, 235, 615
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(126, 855) = 11970
GCD(126, 855) = ( 126 x 855 ) / 11970
= 126 / 855
= 126
Step2:
LCM(9, 235) = 2115
GCD(9, 235) = ( 9 x 235 ) / 2115
= 9 / 235
= 9
Step3:
LCM(1, 615) = 615
GCD(1, 615) = ( 1 x 615 ) / 615
= 1 / 615
= 1
So, Greatest Common Divisor of 126, 855, 235, 615 is 1
