Given numbers are 615, 655, 63, 905
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(615, 655) = 80565
GCD(615, 655) = ( 615 x 655 ) / 80565
= 615 / 655
= 615
Step2:
LCM(5, 63) = 315
GCD(5, 63) = ( 5 x 63 ) / 315
= 5 / 63
= 5
Step3:
LCM(1, 905) = 905
GCD(1, 905) = ( 1 x 905 ) / 905
= 1 / 905
= 1
So, Greatest Common Divisor of 615, 655, 63, 905 is 1
