Given numbers are 400, 450, 516, 630

The list of prime factors of all numbers are

Prime factors of 400 are 2 x 2 x 2 x 2 x 5 x 5

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

Prime factors of 516 are 2 x 2 x 3 x 43

Prime factors of 630 are 2 x 3 x 3 x 5 x 7

The highest common occurrence is 2¹

Therefore, GCD of 400, 450, 516, 630 is 2.

Given numbers are 400, 450, 516, 630

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

Apply this formula for all numbers.

Step1:

LCM(400, 450) = 3600

GCD(400, 450) = ( 400 x 450 ) / 3600

= 400 / 450

= 400

Step2:

LCM(50, 516) = 12900

GCD(50, 516) = ( 50 x 516 ) / 12900

= 50 / 516

= 50

Step3:

LCM(2, 630) = 630

GCD(2, 630) = ( 2 x 630 ) / 630

= 2 / 630

= 2

So, Greatest Common Divisor of 400, 450, 516, 630 is 2
