Given numbers are 490, 216, 157, 730

The list of prime factors of all numbers are

Prime factors of 490 are 2 x 5 x 7 x 7

Prime factors of 216 are 2 x 2 x 2 x 3 x 3 x 3

Prime factors of 157 are 157

Prime factors of 730 are 2 x 5 x 73

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

Given numbers are 490, 216, 157, 730

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

Apply this formula for all numbers.

Step1:

LCM(490, 216) = 52920

GCD(490, 216) = ( 490 x 216 ) / 52920

= 490 / 216

= 490

Step2:

LCM(2, 157) = 314

GCD(2, 157) = ( 2 x 157 ) / 314

= 2 / 157

= 2

Step3:

LCM(1, 730) = 730

GCD(1, 730) = ( 1 x 730 ) / 730

= 1 / 730

= 1

So, Greatest Common Divisor of 490, 216, 157, 730 is 1
