GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(615, 486) = 99630
GCD(615, 486) = ( 615 x 486 ) / 99630
= 615 / 486
= 615
Step2:
LCM(3, 39) = 39
GCD(3, 39) = ( 3 x 39 ) / 39
= 3 / 39
= 3
Step3:
LCM(3, 705) = 705
GCD(3, 705) = ( 3 x 705 ) / 705
= 3 / 705
= 3
So, Greatest Common Divisor of 615, 486, 39, 705 is 3
