Given numbers are 705, 766, 390, 356

The list of prime factors of all numbers are

Prime factors of 705 are 3 x 5 x 47

Prime factors of 766 are 2 x 383

Prime factors of 390 are 2 x 3 x 5 x 13

Prime factors of 356 are 2 x 2 x 89

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

Given numbers are 705, 766, 390, 356

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

Apply this formula for all numbers.

Step1:

LCM(705, 766) = 540030

GCD(705, 766) = ( 705 x 766 ) / 540030

= 705 / 766

= 705

Step2:

LCM(1, 390) = 390

GCD(1, 390) = ( 1 x 390 ) / 390

= 1 / 390

= 1

Step3:

LCM(1, 356) = 356

GCD(1, 356) = ( 1 x 356 ) / 356

= 1 / 356

= 1

So, Greatest Common Divisor of 705, 766, 390, 356 is 1
