Given numbers are 762, 387, 155, 289

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

Apply this formula for all numbers.

Step1:

LCM(762, 387) = 98298

GCD(762, 387) = ( 762 x 387 ) / 98298

= 762 / 387

= 762

Step2:

LCM(3, 155) = 465

GCD(3, 155) = ( 3 x 155 ) / 465

= 3 / 155

= 3

Step3:

LCM(1, 289) = 289

GCD(1, 289) = ( 1 x 289 ) / 289

= 1 / 289

= 1

So, Greatest Common Divisor of 762, 387, 155, 289 is 1
