Given numbers are 100, 554, 644, 450

The list of prime factors of all numbers are

Prime factors of 100 are 2 x 2 x 5 x 5

Prime factors of 554 are 2 x 277

Prime factors of 644 are 2 x 2 x 7 x 23

Prime factors of 450 are 2 x 3 x 3 x 5 x 5

The highest common occurrence is 2¹

Therefore, GCD of 100, 554, 644, 450 is 2.

Given numbers are 100, 554, 644, 450

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

Apply this formula for all numbers.

Step1:

LCM(100, 554) = 27700

GCD(100, 554) = ( 100 x 554 ) / 27700

= 100 / 554

= 100

Step2:

LCM(2, 644) = 644

GCD(2, 644) = ( 2 x 644 ) / 644

= 2 / 644

= 2

Step3:

LCM(2, 450) = 450

GCD(2, 450) = ( 2 x 450 ) / 450

= 2 / 450

= 2

So, Greatest Common Divisor of 100, 554, 644, 450 is 2
