Given numbers are 253, 690, 786, 340

The list of prime factors of all numbers are

Prime factors of 253 are 11 x 23

Prime factors of 690 are 2 x 3 x 5 x 23

Prime factors of 786 are 2 x 3 x 131

Prime factors of 340 are 2 x 2 x 5 x 17

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

Given numbers are 253, 690, 786, 340

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

Apply this formula for all numbers.

Step1:

LCM(253, 690) = 7590

GCD(253, 690) = ( 253 x 690 ) / 7590

= 253 / 690

= 253

Step2:

LCM(23, 786) = 18078

GCD(23, 786) = ( 23 x 786 ) / 18078

= 23 / 786

= 23

Step3:

LCM(1, 340) = 340

GCD(1, 340) = ( 1 x 340 ) / 340

= 1 / 340

= 1

So, Greatest Common Divisor of 253, 690, 786, 340 is 1
