Given numbers are 643, 569, 455, 653

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

Apply this formula for all numbers.

Step1:

LCM(643, 569) = 365867

GCD(643, 569) = ( 643 x 569 ) / 365867

= 643 / 569

= 643

Step2:

LCM(1, 455) = 455

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

= 1 / 455

= 1

Step3:

LCM(1, 653) = 653

GCD(1, 653) = ( 1 x 653 ) / 653

= 1 / 653

= 1

So, Greatest Common Divisor of 643, 569, 455, 653 is 1
