Given numbers are 615, 397, 456, 546
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(615, 397) = 244155
GCD(615, 397) = ( 615 x 397 ) / 244155
= 615 / 397
= 615
Step2:
LCM(1, 456) = 456
GCD(1, 456) = ( 1 x 456 ) / 456
= 1 / 456
= 1
Step3:
LCM(1, 546) = 546
GCD(1, 546) = ( 1 x 546 ) / 546
= 1 / 546
= 1
So, Greatest Common Divisor of 615, 397, 456, 546 is 1
