Given numbers are 689, 478, 641, 608
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(689, 478) = 329342
GCD(689, 478) = ( 689 x 478 ) / 329342
= 689 / 478
= 689
Step2:
LCM(1, 641) = 641
GCD(1, 641) = ( 1 x 641 ) / 641
= 1 / 641
= 1
Step3:
LCM(1, 608) = 608
GCD(1, 608) = ( 1 x 608 ) / 608
= 1 / 608
= 1
So, Greatest Common Divisor of 689, 478, 641, 608 is 1
