Given numbers are 100, 865, 780

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

Apply this formula for all numbers.

Step1:

LCM(100, 865) = 17300

GCD(100, 865) = ( 100 x 865 ) / 17300

= 100 / 865

= 100

Step2:

LCM(5, 780) = 780

GCD(5, 780) = ( 5 x 780 ) / 780

= 5 / 780

= 5

So, Greatest Common Divisor of 100, 865, 780 is 5
