Given numbers are 909, 579, 287, 615
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(909, 579) = 175437
GCD(909, 579) = ( 909 x 579 ) / 175437
= 909 / 579
= 909
Step2:
LCM(3, 287) = 861
GCD(3, 287) = ( 3 x 287 ) / 861
= 3 / 287
= 3
Step3:
LCM(1, 615) = 615
GCD(1, 615) = ( 1 x 615 ) / 615
= 1 / 615
= 1
So, Greatest Common Divisor of 909, 579, 287, 615 is 1
