Given numbers are 840, 175, 807, 787

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 175 are 5 x 5 x 7

Prime factors of 807 are 3 x 269

Prime factors of 787 are 787

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

Given numbers are 840, 175, 807, 787

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

Apply this formula for all numbers.

Step1:

LCM(840, 175) = 4200

GCD(840, 175) = ( 840 x 175 ) / 4200

= 840 / 175

= 840

Step2:

LCM(35, 807) = 28245

GCD(35, 807) = ( 35 x 807 ) / 28245

= 35 / 807

= 35

Step3:

LCM(1, 787) = 787

GCD(1, 787) = ( 1 x 787 ) / 787

= 1 / 787

= 1

So, Greatest Common Divisor of 840, 175, 807, 787 is 1
