GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(861, 492) = 3444
GCD(861, 492) = ( 861 x 492 ) / 3444
= 861 / 492
= 861
Step2:
LCM(123, 690) = 28290
GCD(123, 690) = ( 123 x 690 ) / 28290
= 123 / 690
= 123
Step3:
LCM(3, 927) = 927
GCD(3, 927) = ( 3 x 927 ) / 927
= 3 / 927
= 3
So, Greatest Common Divisor of 861, 492, 690, 927 is 3
