GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(861, 324) = 92988
GCD(861, 324) = ( 861 x 324 ) / 92988
= 861 / 324
= 861
Step2:
LCM(3, 986) = 2958
GCD(3, 986) = ( 3 x 986 ) / 2958
= 3 / 986
= 3
Step3:
LCM(1, 975) = 975
GCD(1, 975) = ( 1 x 975 ) / 975
= 1 / 975
= 1
So, Greatest Common Divisor of 861, 324, 986, 975 is 1
