Given numbers are 861, 690, 185, 451
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(861, 690) = 198030
GCD(861, 690) = ( 861 x 690 ) / 198030
= 861 / 690
= 861
Step2:
LCM(3, 185) = 555
GCD(3, 185) = ( 3 x 185 ) / 555
= 3 / 185
= 3
Step3:
LCM(1, 451) = 451
GCD(1, 451) = ( 1 x 451 ) / 451
= 1 / 451
= 1
So, Greatest Common Divisor of 861, 690, 185, 451 is 1
