Given numbers are 981, 655, 148, 506

The list of prime factors of all numbers are

Prime factors of 981 are 3 x 3 x 109

Prime factors of 655 are 5 x 131

Prime factors of 148 are 2 x 2 x 37

Prime factors of 506 are 2 x 11 x 23

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

Given numbers are 981, 655, 148, 506

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

Apply this formula for all numbers.

Step1:

LCM(981, 655) = 642555

GCD(981, 655) = ( 981 x 655 ) / 642555

= 981 / 655

= 981

Step2:

LCM(1, 148) = 148

GCD(1, 148) = ( 1 x 148 ) / 148

= 1 / 148

= 1

Step3:

LCM(1, 506) = 506

GCD(1, 506) = ( 1 x 506 ) / 506

= 1 / 506

= 1

So, Greatest Common Divisor of 981, 655, 148, 506 is 1
