GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(780, 376) = 73320
GCD(780, 376) = ( 780 x 376 ) / 73320
= 780 / 376
= 780
Step2:
LCM(4, 686) = 1372
GCD(4, 686) = ( 4 x 686 ) / 1372
= 4 / 686
= 4
Step3:
LCM(2, 606) = 606
GCD(2, 606) = ( 2 x 606 ) / 606
= 2 / 606
= 2
So, Greatest Common Divisor of 780, 376, 686, 606 is 2
