Given numbers are 670, 654, 705, 109

The list of prime factors of all numbers are

Prime factors of 670 are 2 x 5 x 67

Prime factors of 654 are 2 x 3 x 109

Prime factors of 705 are 3 x 5 x 47

Prime factors of 109 are 109

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

Given numbers are 670, 654, 705, 109

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

Apply this formula for all numbers.

Step1:

LCM(670, 654) = 219090

GCD(670, 654) = ( 670 x 654 ) / 219090

= 670 / 654

= 670

Step2:

LCM(2, 705) = 1410

GCD(2, 705) = ( 2 x 705 ) / 1410

= 2 / 705

= 2

Step3:

LCM(1, 109) = 109

GCD(1, 109) = ( 1 x 109 ) / 109

= 1 / 109

= 1

So, Greatest Common Divisor of 670, 654, 705, 109 is 1
