Steps to Calculate GCD of 645, 268, 203, 826 using LCM Formula

Given numbers are 645, 268, 203, 826

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

Apply this formula for all numbers.

Step1:

LCM(645, 268) = 172860

GCD(645, 268) = ( 645 x 268 ) / 172860

= 645 / 268

= 645


Step2:

LCM(1, 203) = 203

GCD(1, 203) = ( 1 x 203 ) / 203

= 1 / 203

= 1


Step3:

LCM(1, 826) = 826

GCD(1, 826) = ( 1 x 826 ) / 826

= 1 / 826

= 1


So, Greatest Common Divisor of 645, 268, 203, 826 is 1
