Given numbers are 743, 851, 840, 154

The list of prime factors of all numbers are

Prime factors of 743 are 743

Prime factors of 851 are 23 x 37

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

Prime factors of 154 are 2 x 7 x 11

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

Given numbers are 743, 851, 840, 154

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

Apply this formula for all numbers.

Step1:

LCM(743, 851) = 632293

GCD(743, 851) = ( 743 x 851 ) / 632293

= 743 / 851

= 743

Step2:

LCM(1, 840) = 840

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

= 1 / 840

= 1

Step3:

LCM(1, 154) = 154

GCD(1, 154) = ( 1 x 154 ) / 154

= 1 / 154

= 1

So, Greatest Common Divisor of 743, 851, 840, 154 is 1
