Given numbers are 427, 172, 105, 673

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

Apply this formula for all numbers.

Step1:

LCM(427, 172) = 73444

GCD(427, 172) = ( 427 x 172 ) / 73444

= 427 / 172

= 427

Step2:

LCM(1, 105) = 105

GCD(1, 105) = ( 1 x 105 ) / 105

= 1 / 105

= 1

Step3:

LCM(1, 673) = 673

GCD(1, 673) = ( 1 x 673 ) / 673

= 1 / 673

= 1

So, Greatest Common Divisor of 427, 172, 105, 673 is 1
