Given numbers are 215, 159, 540, 770

The list of prime factors of all numbers are

Prime factors of 215 are 5 x 43

Prime factors of 159 are 3 x 53

Prime factors of 540 are 2 x 2 x 3 x 3 x 3 x 5

Prime factors of 770 are 2 x 5 x 7 x 11

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

Given numbers are 215, 159, 540, 770

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

Apply this formula for all numbers.

Step1:

LCM(215, 159) = 34185

GCD(215, 159) = ( 215 x 159 ) / 34185

= 215 / 159

= 215

Step2:

LCM(1, 540) = 540

GCD(1, 540) = ( 1 x 540 ) / 540

= 1 / 540

= 1

Step3:

LCM(1, 770) = 770

GCD(1, 770) = ( 1 x 770 ) / 770

= 1 / 770

= 1

So, Greatest Common Divisor of 215, 159, 540, 770 is 1
