Given numbers are 424, 670, 987, 210

The list of prime factors of all numbers are

Prime factors of 424 are 2 x 2 x 2 x 53

Prime factors of 670 are 2 x 5 x 67

Prime factors of 987 are 3 x 7 x 47

Prime factors of 210 are 2 x 3 x 5 x 7

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

Given numbers are 424, 670, 987, 210

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

Apply this formula for all numbers.

Step1:

LCM(424, 670) = 142040

GCD(424, 670) = ( 424 x 670 ) / 142040

= 424 / 670

= 424

Step2:

LCM(2, 987) = 1974

GCD(2, 987) = ( 2 x 987 ) / 1974

= 2 / 987

= 2

Step3:

LCM(1, 210) = 210

GCD(1, 210) = ( 1 x 210 ) / 210

= 1 / 210

= 1

So, Greatest Common Divisor of 424, 670, 987, 210 is 1
