Given numbers are 189, 561, 344, 751

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

Apply this formula for all numbers.

Step1:

LCM(189, 561) = 35343

GCD(189, 561) = ( 189 x 561 ) / 35343

= 189 / 561

= 189

Step2:

LCM(3, 344) = 1032

GCD(3, 344) = ( 3 x 344 ) / 1032

= 3 / 344

= 3

Step3:

LCM(1, 751) = 751

GCD(1, 751) = ( 1 x 751 ) / 751

= 1 / 751

= 1

So, Greatest Common Divisor of 189, 561, 344, 751 is 1
