GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(521, 499) = 259979
GCD(521, 499) = ( 521 x 499 ) / 259979
= 521 / 499
= 521
Step2:
LCM(1, 435) = 435
GCD(1, 435) = ( 1 x 435 ) / 435
= 1 / 435
= 1
Step3:
LCM(1, 780) = 780
GCD(1, 780) = ( 1 x 780 ) / 780
= 1 / 780
= 1
So, Greatest Common Divisor of 521, 499, 435, 780 is 1
