Given numbers are 861, 753, 424, 861
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(861, 753) = 216111
GCD(861, 753) = ( 861 x 753 ) / 216111
= 861 / 753
= 861
Step2:
LCM(3, 424) = 1272
GCD(3, 424) = ( 3 x 424 ) / 1272
= 3 / 424
= 3
Step3:
LCM(1, 861) = 861
GCD(1, 861) = ( 1 x 861 ) / 861
= 1 / 861
= 1
So, Greatest Common Divisor of 861, 753, 424, 861 is 1
