Given numbers are 781, 990, 387, 150

The list of prime factors of all numbers are

Prime factors of 781 are 11 x 71

Prime factors of 990 are 2 x 3 x 3 x 5 x 11

Prime factors of 387 are 3 x 3 x 43

Prime factors of 150 are 2 x 3 x 5 x 5

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

Given numbers are 781, 990, 387, 150

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

Apply this formula for all numbers.

Step1:

LCM(781, 990) = 70290

GCD(781, 990) = ( 781 x 990 ) / 70290

= 781 / 990

= 781

Step2:

LCM(11, 387) = 4257

GCD(11, 387) = ( 11 x 387 ) / 4257

= 11 / 387

= 11

Step3:

LCM(1, 150) = 150

GCD(1, 150) = ( 1 x 150 ) / 150

= 1 / 150

= 1

So, Greatest Common Divisor of 781, 990, 387, 150 is 1
