Given numbers are 727, 648, 639, 501
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(727, 648) = 471096
GCD(727, 648) = ( 727 x 648 ) / 471096
= 727 / 648
= 727
Step2:
LCM(1, 639) = 639
GCD(1, 639) = ( 1 x 639 ) / 639
= 1 / 639
= 1
Step3:
LCM(1, 501) = 501
GCD(1, 501) = ( 1 x 501 ) / 501
= 1 / 501
= 1
So, Greatest Common Divisor of 727, 648, 639, 501 is 1
