Given numbers are 655, 815, 61

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

Apply this formula for all numbers.

Step1:

LCM(655, 815) = 106765

GCD(655, 815) = ( 655 x 815 ) / 106765

= 655 / 815

= 655

Step2:

LCM(5, 61) = 305

GCD(5, 61) = ( 5 x 61 ) / 305

= 5 / 61

= 5

So, Greatest Common Divisor of 655, 815, 61 is 1
