Given numbers are 865, 515, 847, 573
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(865, 515) = 89095
GCD(865, 515) = ( 865 x 515 ) / 89095
= 865 / 515
= 865
Step2:
LCM(5, 847) = 4235
GCD(5, 847) = ( 5 x 847 ) / 4235
= 5 / 847
= 5
Step3:
LCM(1, 573) = 573
GCD(1, 573) = ( 1 x 573 ) / 573
= 1 / 573
= 1
So, Greatest Common Divisor of 865, 515, 847, 573 is 1
