Steps to Calculate GCD of 630, 321, 190, 691 using LCM Formula

Given numbers are 630, 321, 190, 691

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(630, 321) = 67410

GCD(630, 321) = ( 630 x 321 ) / 67410

= 630 / 321

= 630


Step2:

LCM(3, 190) = 570

GCD(3, 190) = ( 3 x 190 ) / 570

= 3 / 190

= 3


Step3:

LCM(1, 691) = 691

GCD(1, 691) = ( 1 x 691 ) / 691

= 1 / 691

= 1


So, Greatest Common Divisor of 630, 321, 190, 691 is 1
