Given numbers are 823, 647, 205, 890
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(823, 647) = 532481
GCD(823, 647) = ( 823 x 647 ) / 532481
= 823 / 647
= 823
Step2:
LCM(1, 205) = 205
GCD(1, 205) = ( 1 x 205 ) / 205
= 1 / 205
= 1
Step3:
LCM(1, 890) = 890
GCD(1, 890) = ( 1 x 890 ) / 890
= 1 / 890
= 1
So, Greatest Common Divisor of 823, 647, 205, 890 is 1
