Given numbers are 491, 429, 642, 275

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

Apply this formula for all numbers.

Step1:

LCM(491, 429) = 210639

GCD(491, 429) = ( 491 x 429 ) / 210639

= 491 / 429

= 491

Step2:

LCM(1, 642) = 642

GCD(1, 642) = ( 1 x 642 ) / 642

= 1 / 642

= 1

Step3:

LCM(1, 275) = 275

GCD(1, 275) = ( 1 x 275 ) / 275

= 1 / 275

= 1

So, Greatest Common Divisor of 491, 429, 642, 275 is 1
