Given numbers are 823, 420, 544, 847
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(823, 420) = 345660
GCD(823, 420) = ( 823 x 420 ) / 345660
= 823 / 420
= 823
Step2:
LCM(1, 544) = 544
GCD(1, 544) = ( 1 x 544 ) / 544
= 1 / 544
= 1
Step3:
LCM(1, 847) = 847
GCD(1, 847) = ( 1 x 847 ) / 847
= 1 / 847
= 1
So, Greatest Common Divisor of 823, 420, 544, 847 is 1
