GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(495, 790) = 78210
GCD(495, 790) = ( 495 x 790 ) / 78210
= 495 / 790
= 495
Step2:
LCM(5, 221) = 1105
GCD(5, 221) = ( 5 x 221 ) / 1105
= 5 / 221
= 5
Step3:
LCM(1, 987) = 987
GCD(1, 987) = ( 1 x 987 ) / 987
= 1 / 987
= 1
So, Greatest Common Divisor of 495, 790, 221, 987 is 1
