Given numbers are 743, 124, 775, 455

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

Apply this formula for all numbers.

Step1:

LCM(743, 124) = 92132

GCD(743, 124) = ( 743 x 124 ) / 92132

= 743 / 124

= 743

Step2:

LCM(1, 775) = 775

GCD(1, 775) = ( 1 x 775 ) / 775

= 1 / 775

= 1

Step3:

LCM(1, 455) = 455

GCD(1, 455) = ( 1 x 455 ) / 455

= 1 / 455

= 1

So, Greatest Common Divisor of 743, 124, 775, 455 is 1
