Given numbers are 312, 537, 172, 781

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

Apply this formula for all numbers.

Step1:

LCM(312, 537) = 55848

GCD(312, 537) = ( 312 x 537 ) / 55848

= 312 / 537

= 312

Step2:

LCM(3, 172) = 516

GCD(3, 172) = ( 3 x 172 ) / 516

= 3 / 172

= 3

Step3:

LCM(1, 781) = 781

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

= 1 / 781

= 1

So, Greatest Common Divisor of 312, 537, 172, 781 is 1
