Given numbers are 502, 126, 755, 421
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(502, 126) = 31626
GCD(502, 126) = ( 502 x 126 ) / 31626
= 502 / 126
= 502
Step2:
LCM(2, 755) = 1510
GCD(2, 755) = ( 2 x 755 ) / 1510
= 2 / 755
= 2
Step3:
LCM(1, 421) = 421
GCD(1, 421) = ( 1 x 421 ) / 421
= 1 / 421
= 1
So, Greatest Common Divisor of 502, 126, 755, 421 is 1
