Given numbers are 823, 861, 280, 802
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(823, 861) = 708603
GCD(823, 861) = ( 823 x 861 ) / 708603
= 823 / 861
= 823
Step2:
LCM(1, 280) = 280
GCD(1, 280) = ( 1 x 280 ) / 280
= 1 / 280
= 1
Step3:
LCM(1, 802) = 802
GCD(1, 802) = ( 1 x 802 ) / 802
= 1 / 802
= 1
So, Greatest Common Divisor of 823, 861, 280, 802 is 1
