Given numbers are 407, 695, 840, 603

The list of prime factors of all numbers are

Prime factors of 407 are 11 x 37

Prime factors of 695 are 5 x 139

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

Prime factors of 603 are 3 x 3 x 67

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

Given numbers are 407, 695, 840, 603

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

Apply this formula for all numbers.

Step1:

LCM(407, 695) = 282865

GCD(407, 695) = ( 407 x 695 ) / 282865

= 407 / 695

= 407

Step2:

LCM(1, 840) = 840

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

= 1 / 840

= 1

Step3:

LCM(1, 603) = 603

GCD(1, 603) = ( 1 x 603 ) / 603

= 1 / 603

= 1

So, Greatest Common Divisor of 407, 695, 840, 603 is 1
