Given numbers are 725, 355, 370, 129
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(725, 355) = 51475
GCD(725, 355) = ( 725 x 355 ) / 51475
= 725 / 355
= 725
Step2:
LCM(5, 370) = 370
GCD(5, 370) = ( 5 x 370 ) / 370
= 5 / 370
= 5
Step3:
LCM(5, 129) = 645
GCD(5, 129) = ( 5 x 129 ) / 645
= 5 / 129
= 5
So, Greatest Common Divisor of 725, 355, 370, 129 is 1
