Given numbers are 516, 778, 351, 420
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(516, 778) = 200724
GCD(516, 778) = ( 516 x 778 ) / 200724
= 516 / 778
= 516
Step2:
LCM(2, 351) = 702
GCD(2, 351) = ( 2 x 351 ) / 702
= 2 / 351
= 2
Step3:
LCM(1, 420) = 420
GCD(1, 420) = ( 1 x 420 ) / 420
= 1 / 420
= 1
So, Greatest Common Divisor of 516, 778, 351, 420 is 1
