Given numbers are 143, 742, 660, 462

The list of prime factors of all numbers are

Prime factors of 143 are 11 x 13

Prime factors of 742 are 2 x 7 x 53

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

Prime factors of 462 are 2 x 3 x 7 x 11

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

Given numbers are 143, 742, 660, 462

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

Apply this formula for all numbers.

Step1:

LCM(143, 742) = 106106

GCD(143, 742) = ( 143 x 742 ) / 106106

= 143 / 742

= 143

Step2:

LCM(1, 660) = 660

GCD(1, 660) = ( 1 x 660 ) / 660

= 1 / 660

= 1

Step3:

LCM(1, 462) = 462

GCD(1, 462) = ( 1 x 462 ) / 462

= 1 / 462

= 1

So, Greatest Common Divisor of 143, 742, 660, 462 is 1
