Given numbers are 655, 693, 581, 670

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

Apply this formula for all numbers.

Step1:

LCM(655, 693) = 453915

GCD(655, 693) = ( 655 x 693 ) / 453915

= 655 / 693

= 655

Step2:

LCM(1, 581) = 581

GCD(1, 581) = ( 1 x 581 ) / 581

= 1 / 581

= 1

Step3:

LCM(1, 670) = 670

GCD(1, 670) = ( 1 x 670 ) / 670

= 1 / 670

= 1

So, Greatest Common Divisor of 655, 693, 581, 670 is 1
