Given numbers are 695, 725, 220, 670

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

Apply this formula for all numbers.

Step1:

LCM(695, 725) = 100775

GCD(695, 725) = ( 695 x 725 ) / 100775

= 695 / 725

= 695

Step2:

LCM(5, 220) = 220

GCD(5, 220) = ( 5 x 220 ) / 220

= 5 / 220

= 5

Step3:

LCM(5, 670) = 670

GCD(5, 670) = ( 5 x 670 ) / 670

= 5 / 670

= 5

So, Greatest Common Divisor of 695, 725, 220, 670 is 5
