Given numbers are 421, 575, 132, 840

The list of prime factors of all numbers are

Prime factors of 421 are 421

Prime factors of 575 are 5 x 5 x 23

Prime factors of 132 are 2 x 2 x 3 x 11

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 421, 575, 132, 840

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

Apply this formula for all numbers.

Step1:

LCM(421, 575) = 242075

GCD(421, 575) = ( 421 x 575 ) / 242075

= 421 / 575

= 421

Step2:

LCM(1, 132) = 132

GCD(1, 132) = ( 1 x 132 ) / 132

= 1 / 132

= 1

Step3:

LCM(1, 840) = 840

GCD(1, 840) = ( 1 x 840 ) / 840

= 1 / 840

= 1

So, Greatest Common Divisor of 421, 575, 132, 840 is 1
