GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(615, 686) = 421890
GCD(615, 686) = ( 615 x 686 ) / 421890
= 615 / 686
= 615
Step2:
LCM(1, 587) = 587
GCD(1, 587) = ( 1 x 587 ) / 587
= 1 / 587
= 1
Step3:
LCM(1, 580) = 580
GCD(1, 580) = ( 1 x 580 ) / 580
= 1 / 580
= 1
So, Greatest Common Divisor of 615, 686, 587, 580 is 1
