Given numbers are 725, 162, 878, 641
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(725, 162) = 117450
GCD(725, 162) = ( 725 x 162 ) / 117450
= 725 / 162
= 725
Step2:
LCM(1, 878) = 878
GCD(1, 878) = ( 1 x 878 ) / 878
= 1 / 878
= 1
Step3:
LCM(1, 641) = 641
GCD(1, 641) = ( 1 x 641 ) / 641
= 1 / 641
= 1
So, Greatest Common Divisor of 725, 162, 878, 641 is 1
