Given numbers are 145, 716, 781

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

Apply this formula for all numbers.

Step1:

LCM(145, 716) = 103820

GCD(145, 716) = ( 145 x 716 ) / 103820

= 145 / 716

= 145

Step2:

LCM(1, 781) = 781

GCD(1, 781) = ( 1 x 781 ) / 781

= 1 / 781

= 1

So, Greatest Common Divisor of 145, 716, 781 is 1
