Given numbers are 420, 547, 907, 783

The list of prime factors of all numbers are

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

Prime factors of 547 are 547

Prime factors of 907 are 907

Prime factors of 783 are 3 x 3 x 3 x 29

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

Given numbers are 420, 547, 907, 783

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

Apply this formula for all numbers.

Step1:

LCM(420, 547) = 229740

GCD(420, 547) = ( 420 x 547 ) / 229740

= 420 / 547

= 420

Step2:

LCM(1, 907) = 907

GCD(1, 907) = ( 1 x 907 ) / 907

= 1 / 907

= 1

Step3:

LCM(1, 783) = 783

GCD(1, 783) = ( 1 x 783 ) / 783

= 1 / 783

= 1

So, Greatest Common Divisor of 420, 547, 907, 783 is 1
