Given numbers are 861, 101, 945, 186
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(861, 101) = 86961
GCD(861, 101) = ( 861 x 101 ) / 86961
= 861 / 101
= 861
Step2:
LCM(1, 945) = 945
GCD(1, 945) = ( 1 x 945 ) / 945
= 1 / 945
= 1
Step3:
LCM(1, 186) = 186
GCD(1, 186) = ( 1 x 186 ) / 186
= 1 / 186
= 1
So, Greatest Common Divisor of 861, 101, 945, 186 is 1
