Given numbers are 689, 130, 843, 157
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(689, 130) = 6890
GCD(689, 130) = ( 689 x 130 ) / 6890
= 689 / 130
= 689
Step2:
LCM(13, 843) = 10959
GCD(13, 843) = ( 13 x 843 ) / 10959
= 13 / 843
= 13
Step3:
LCM(1, 157) = 157
GCD(1, 157) = ( 1 x 157 ) / 157
= 1 / 157
= 1
So, Greatest Common Divisor of 689, 130, 843, 157 is 1
