GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(391, 679) = 265489
GCD(391, 679) = ( 391 x 679 ) / 265489
= 391 / 679
= 391
Step2:
LCM(1, 221) = 221
GCD(1, 221) = ( 1 x 221 ) / 221
= 1 / 221
= 1
Step3:
LCM(1, 599) = 599
GCD(1, 599) = ( 1 x 599 ) / 599
= 1 / 599
= 1
So, Greatest Common Divisor of 391, 679, 221, 599 is 1
