Given numbers are 215, 130, 430, 746

The list of prime factors of all numbers are

Prime factors of 215 are 5 x 43

Prime factors of 130 are 2 x 5 x 13

Prime factors of 430 are 2 x 5 x 43

Prime factors of 746 are 2 x 373

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

Given numbers are 215, 130, 430, 746

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

Apply this formula for all numbers.

Step1:

LCM(215, 130) = 5590

GCD(215, 130) = ( 215 x 130 ) / 5590

= 215 / 130

= 215

Step2:

LCM(5, 430) = 430

GCD(5, 430) = ( 5 x 430 ) / 430

= 5 / 430

= 5

Step3:

LCM(5, 746) = 3730

GCD(5, 746) = ( 5 x 746 ) / 3730

= 5 / 746

= 5

So, Greatest Common Divisor of 215, 130, 430, 746 is 1
