Given numbers are 109, 644, 356

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

Apply this formula for all numbers.

Step1:

LCM(109, 644) = 70196

GCD(109, 644) = ( 109 x 644 ) / 70196

= 109 / 644

= 109

Step2:

LCM(1, 356) = 356

GCD(1, 356) = ( 1 x 356 ) / 356

= 1 / 356

= 1

So, Greatest Common Divisor of 109, 644, 356 is 1
