Given numbers are 689, 379, 156, 895
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(689, 379) = 261131
GCD(689, 379) = ( 689 x 379 ) / 261131
= 689 / 379
= 689
Step2:
LCM(1, 156) = 156
GCD(1, 156) = ( 1 x 156 ) / 156
= 1 / 156
= 1
Step3:
LCM(1, 895) = 895
GCD(1, 895) = ( 1 x 895 ) / 895
= 1 / 895
= 1
So, Greatest Common Divisor of 689, 379, 156, 895 is 1
