Given numbers are 840, 402, 207, 731

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 402 are 2 x 3 x 67

Prime factors of 207 are 3 x 3 x 23

Prime factors of 731 are 17 x 43

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

Given numbers are 840, 402, 207, 731

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

Apply this formula for all numbers.

Step1:

LCM(840, 402) = 56280

GCD(840, 402) = ( 840 x 402 ) / 56280

= 840 / 402

= 840

Step2:

LCM(6, 207) = 414

GCD(6, 207) = ( 6 x 207 ) / 414

= 6 / 207

= 6

Step3:

LCM(3, 731) = 2193

GCD(3, 731) = ( 3 x 731 ) / 2193

= 3 / 731

= 3

So, Greatest Common Divisor of 840, 402, 207, 731 is 1
