Given numbers are 190, 657, 643, 659

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

Apply this formula for all numbers.

Step1:

LCM(190, 657) = 124830

GCD(190, 657) = ( 190 x 657 ) / 124830

= 190 / 657

= 190

Step2:

LCM(1, 643) = 643

GCD(1, 643) = ( 1 x 643 ) / 643

= 1 / 643

= 1

Step3:

LCM(1, 659) = 659

GCD(1, 659) = ( 1 x 659 ) / 659

= 1 / 659

= 1

So, Greatest Common Divisor of 190, 657, 643, 659 is 1
