Given numbers are 840, 387, 141, 326

The list of prime factors of all numbers are

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

Prime factors of 387 are 3 x 3 x 43

Prime factors of 141 are 3 x 47

Prime factors of 326 are 2 x 163

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

Given numbers are 840, 387, 141, 326

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

Apply this formula for all numbers.

Step1:

LCM(840, 387) = 108360

GCD(840, 387) = ( 840 x 387 ) / 108360

= 840 / 387

= 840

Step2:

LCM(3, 141) = 141

GCD(3, 141) = ( 3 x 141 ) / 141

= 3 / 141

= 3

Step3:

LCM(3, 326) = 978

GCD(3, 326) = ( 3 x 326 ) / 978

= 3 / 326

= 3

So, Greatest Common Divisor of 840, 387, 141, 326 is 1
