Given numbers are 561, 865, 654, 744
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(561, 865) = 485265
GCD(561, 865) = ( 561 x 865 ) / 485265
= 561 / 865
= 561
Step2:
LCM(1, 654) = 654
GCD(1, 654) = ( 1 x 654 ) / 654
= 1 / 654
= 1
Step3:
LCM(1, 744) = 744
GCD(1, 744) = ( 1 x 744 ) / 744
= 1 / 744
= 1
So, Greatest Common Divisor of 561, 865, 654, 744 is 1
