Given numbers are 641, 563, 434, 826

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

Apply this formula for all numbers.

Step1:

LCM(641, 563) = 360883

GCD(641, 563) = ( 641 x 563 ) / 360883

= 641 / 563

= 641

Step2:

LCM(1, 434) = 434

GCD(1, 434) = ( 1 x 434 ) / 434

= 1 / 434

= 1

Step3:

LCM(1, 826) = 826

GCD(1, 826) = ( 1 x 826 ) / 826

= 1 / 826

= 1

So, Greatest Common Divisor of 641, 563, 434, 826 is 1
