Given numbers are 125, 815, 398, 357
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(125, 815) = 20375
GCD(125, 815) = ( 125 x 815 ) / 20375
= 125 / 815
= 125
Step2:
LCM(5, 398) = 1990
GCD(5, 398) = ( 5 x 398 ) / 1990
= 5 / 398
= 5
Step3:
LCM(1, 357) = 357
GCD(1, 357) = ( 1 x 357 ) / 357
= 1 / 357
= 1
So, Greatest Common Divisor of 125, 815, 398, 357 is 1
