Given numbers are 345, 619, 128, 859

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

Apply this formula for all numbers.

Step1:

LCM(345, 619) = 213555

GCD(345, 619) = ( 345 x 619 ) / 213555

= 345 / 619

= 345

Step2:

LCM(1, 128) = 128

GCD(1, 128) = ( 1 x 128 ) / 128

= 1 / 128

= 1

Step3:

LCM(1, 859) = 859

GCD(1, 859) = ( 1 x 859 ) / 859

= 1 / 859

= 1

So, Greatest Common Divisor of 345, 619, 128, 859 is 1
