Given numbers are 730, 890, 557, 155

The list of prime factors of all numbers are

Prime factors of 730 are 2 x 5 x 73

Prime factors of 890 are 2 x 5 x 89

Prime factors of 557 are 557

Prime factors of 155 are 5 x 31

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

Given numbers are 730, 890, 557, 155

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

Apply this formula for all numbers.

Step1:

LCM(730, 890) = 64970

GCD(730, 890) = ( 730 x 890 ) / 64970

= 730 / 890

= 730

Step2:

LCM(10, 557) = 5570

GCD(10, 557) = ( 10 x 557 ) / 5570

= 10 / 557

= 10

Step3:

LCM(1, 155) = 155

GCD(1, 155) = ( 1 x 155 ) / 155

= 1 / 155

= 1

So, Greatest Common Divisor of 730, 890, 557, 155 is 1
