Given numbers are 875, 395, 630, 231
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(875, 395) = 69125
GCD(875, 395) = ( 875 x 395 ) / 69125
= 875 / 395
= 875
Step2:
LCM(5, 630) = 630
GCD(5, 630) = ( 5 x 630 ) / 630
= 5 / 630
= 5
Step3:
LCM(5, 231) = 1155
GCD(5, 231) = ( 5 x 231 ) / 1155
= 5 / 231
= 5
So, Greatest Common Divisor of 875, 395, 630, 231 is 1
