Given numbers are 125, 455, 181, 747

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

Apply this formula for all numbers.

Step1:

LCM(125, 455) = 11375

GCD(125, 455) = ( 125 x 455 ) / 11375

= 125 / 455

= 125

Step2:

LCM(5, 181) = 905

GCD(5, 181) = ( 5 x 181 ) / 905

= 5 / 181

= 5

Step3:

LCM(1, 747) = 747

GCD(1, 747) = ( 1 x 747 ) / 747

= 1 / 747

= 1

So, Greatest Common Divisor of 125, 455, 181, 747 is 1
