Given numbers are 615, 423, 199, 956
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(615, 423) = 86715
GCD(615, 423) = ( 615 x 423 ) / 86715
= 615 / 423
= 615
Step2:
LCM(3, 199) = 597
GCD(3, 199) = ( 3 x 199 ) / 597
= 3 / 199
= 3
Step3:
LCM(1, 956) = 956
GCD(1, 956) = ( 1 x 956 ) / 956
= 1 / 956
= 1
So, Greatest Common Divisor of 615, 423, 199, 956 is 1
