Given numbers are 390, 591, 626, 137
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(390, 591) = 76830
GCD(390, 591) = ( 390 x 591 ) / 76830
= 390 / 591
= 390
Step2:
LCM(3, 626) = 1878
GCD(3, 626) = ( 3 x 626 ) / 1878
= 3 / 626
= 3
Step3:
LCM(1, 137) = 137
GCD(1, 137) = ( 1 x 137 ) / 137
= 1 / 137
= 1
So, Greatest Common Divisor of 390, 591, 626, 137 is 1
