Given numbers are 707, 661, 644, 454

The list of prime factors of all numbers are

Prime factors of 707 are 7 x 101

Prime factors of 661 are 661

Prime factors of 644 are 2 x 2 x 7 x 23

Prime factors of 454 are 2 x 227

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

Given numbers are 707, 661, 644, 454

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

Apply this formula for all numbers.

Step1:

LCM(707, 661) = 467327

GCD(707, 661) = ( 707 x 661 ) / 467327

= 707 / 661

= 707

Step2:

LCM(1, 644) = 644

GCD(1, 644) = ( 1 x 644 ) / 644

= 1 / 644

= 1

Step3:

LCM(1, 454) = 454

GCD(1, 454) = ( 1 x 454 ) / 454

= 1 / 454

= 1

So, Greatest Common Divisor of 707, 661, 644, 454 is 1
