Steps to Calculate GCD of 538, 351, 838, 391 using LCM Formula

Given numbers are 538, 351, 838, 391

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

Apply this formula for all numbers.

Step1:

LCM(538, 351) = 188838

GCD(538, 351) = ( 538 x 351 ) / 188838

= 538 / 351

= 538


Step2:

LCM(1, 838) = 838

GCD(1, 838) = ( 1 x 838 ) / 838

= 1 / 838

= 1


Step3:

LCM(1, 391) = 391

GCD(1, 391) = ( 1 x 391 ) / 391

= 1 / 391

= 1


So, Greatest Common Divisor of 538, 351, 838, 391 is 1
