Given numbers are 550, 920, 156, 905

The list of prime factors of all numbers are

Prime factors of 550 are 2 x 5 x 5 x 11

Prime factors of 920 are 2 x 2 x 2 x 5 x 23

Prime factors of 156 are 2 x 2 x 3 x 13

Prime factors of 905 are 5 x 181

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

Given numbers are 550, 920, 156, 905

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

Apply this formula for all numbers.

Step1:

LCM(550, 920) = 50600

GCD(550, 920) = ( 550 x 920 ) / 50600

= 550 / 920

= 550

Step2:

LCM(10, 156) = 780

GCD(10, 156) = ( 10 x 156 ) / 780

= 10 / 156

= 10

Step3:

LCM(2, 905) = 1810

GCD(2, 905) = ( 2 x 905 ) / 1810

= 2 / 905

= 2

So, Greatest Common Divisor of 550, 920, 156, 905 is 1
