Given numbers are 680, 854, 691, 392
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(680, 854) = 290360
GCD(680, 854) = ( 680 x 854 ) / 290360
= 680 / 854
= 680
Step2:
LCM(2, 691) = 1382
GCD(2, 691) = ( 2 x 691 ) / 1382
= 2 / 691
= 2
Step3:
LCM(1, 392) = 392
GCD(1, 392) = ( 1 x 392 ) / 392
= 1 / 392
= 1
So, Greatest Common Divisor of 680, 854, 691, 392 is 1
