Given numbers are 195, 780, 109

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

Apply this formula for all numbers.

Step1:

LCM(195, 780) = 780

GCD(195, 780) = ( 195 x 780 ) / 780

= 195 / 780

= 195

Step2:

LCM(195, 109) = 21255

GCD(195, 109) = ( 195 x 109 ) / 21255

= 195 / 109

= 195

So, Greatest Common Divisor of 195, 780, 109 is 1
