Given numbers are 143, 456, 620, 681

The list of prime factors of all numbers are

Prime factors of 143 are 11 x 13

Prime factors of 456 are 2 x 2 x 2 x 3 x 19

Prime factors of 620 are 2 x 2 x 5 x 31

Prime factors of 681 are 3 x 227

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

Given numbers are 143, 456, 620, 681

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

Apply this formula for all numbers.

Step1:

LCM(143, 456) = 65208

GCD(143, 456) = ( 143 x 456 ) / 65208

= 143 / 456

= 143

Step2:

LCM(1, 620) = 620

GCD(1, 620) = ( 1 x 620 ) / 620

= 1 / 620

= 1

Step3:

LCM(1, 681) = 681

GCD(1, 681) = ( 1 x 681 ) / 681

= 1 / 681

= 1

So, Greatest Common Divisor of 143, 456, 620, 681 is 1
