Given numbers are 990, 195, 615, 703
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(990, 195) = 12870
GCD(990, 195) = ( 990 x 195 ) / 12870
= 990 / 195
= 990
Step2:
LCM(15, 615) = 615
GCD(15, 615) = ( 15 x 615 ) / 615
= 15 / 615
= 15
Step3:
LCM(15, 703) = 10545
GCD(15, 703) = ( 15 x 703 ) / 10545
= 15 / 703
= 15
So, Greatest Common Divisor of 990, 195, 615, 703 is 1
