Given numbers are 563, 636, 629, 821
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(563, 636) = 358068
GCD(563, 636) = ( 563 x 636 ) / 358068
= 563 / 636
= 563
Step2:
LCM(1, 629) = 629
GCD(1, 629) = ( 1 x 629 ) / 629
= 1 / 629
= 1
Step3:
LCM(1, 821) = 821
GCD(1, 821) = ( 1 x 821 ) / 821
= 1 / 821
= 1
So, Greatest Common Divisor of 563, 636, 629, 821 is 1
