Given numbers are 503, 646, 399, 724
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(503, 646) = 324938
GCD(503, 646) = ( 503 x 646 ) / 324938
= 503 / 646
= 503
Step2:
LCM(1, 399) = 399
GCD(1, 399) = ( 1 x 399 ) / 399
= 1 / 399
= 1
Step3:
LCM(1, 724) = 724
GCD(1, 724) = ( 1 x 724 ) / 724
= 1 / 724
= 1
So, Greatest Common Divisor of 503, 646, 399, 724 is 1
