Given numbers are 782, 620, 641, 446
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(782, 620) = 242420
GCD(782, 620) = ( 782 x 620 ) / 242420
= 782 / 620
= 782
Step2:
LCM(2, 641) = 1282
GCD(2, 641) = ( 2 x 641 ) / 1282
= 2 / 641
= 2
Step3:
LCM(1, 446) = 446
GCD(1, 446) = ( 1 x 446 ) / 446
= 1 / 446
= 1
So, Greatest Common Divisor of 782, 620, 641, 446 is 1
