Given numbers are 567, 651, 720, 784
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(567, 651) = 17577
GCD(567, 651) = ( 567 x 651 ) / 17577
= 567 / 651
= 567
Step2:
LCM(21, 720) = 5040
GCD(21, 720) = ( 21 x 720 ) / 5040
= 21 / 720
= 21
Step3:
LCM(3, 784) = 2352
GCD(3, 784) = ( 3 x 784 ) / 2352
= 3 / 784
= 3
So, Greatest Common Divisor of 567, 651, 720, 784 is 1
