Given numbers are 415, 340, 649, 402

The list of prime factors of all numbers are

Prime factors of 415 are 5 x 83

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

Prime factors of 649 are 11 x 59

Prime factors of 402 are 2 x 3 x 67

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

Given numbers are 415, 340, 649, 402

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

Apply this formula for all numbers.

Step1:

LCM(415, 340) = 28220

GCD(415, 340) = ( 415 x 340 ) / 28220

= 415 / 340

= 415

Step2:

LCM(5, 649) = 3245

GCD(5, 649) = ( 5 x 649 ) / 3245

= 5 / 649

= 5

Step3:

LCM(1, 402) = 402

GCD(1, 402) = ( 1 x 402 ) / 402

= 1 / 402

= 1

So, Greatest Common Divisor of 415, 340, 649, 402 is 1
