Given numbers are 561, 185, 564, 626
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(561, 185) = 103785
GCD(561, 185) = ( 561 x 185 ) / 103785
= 561 / 185
= 561
Step2:
LCM(1, 564) = 564
GCD(1, 564) = ( 1 x 564 ) / 564
= 1 / 564
= 1
Step3:
LCM(1, 626) = 626
GCD(1, 626) = ( 1 x 626 ) / 626
= 1 / 626
= 1
So, Greatest Common Divisor of 561, 185, 564, 626 is 1
