Given numbers are 515, 427, 503, 643
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(515, 427) = 219905
GCD(515, 427) = ( 515 x 427 ) / 219905
= 515 / 427
= 515
Step2:
LCM(1, 503) = 503
GCD(1, 503) = ( 1 x 503 ) / 503
= 1 / 503
= 1
Step3:
LCM(1, 643) = 643
GCD(1, 643) = ( 1 x 643 ) / 643
= 1 / 643
= 1
So, Greatest Common Divisor of 515, 427, 503, 643 is 1
