Given numbers are 247, 218, 61

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

Apply this formula for all numbers.

Step1:

LCM(247, 218) = 53846

GCD(247, 218) = ( 247 x 218 ) / 53846

= 247 / 218

= 247

Step2:

LCM(1, 61) = 61

GCD(1, 61) = ( 1 x 61 ) / 61

= 1 / 61

= 1

So, Greatest Common Divisor of 247, 218, 61 is 1
