Given numbers are 210, 981, 409, 659
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(210, 981) = 68670
GCD(210, 981) = ( 210 x 981 ) / 68670
= 210 / 981
= 210
Step2:
LCM(3, 409) = 1227
GCD(3, 409) = ( 3 x 409 ) / 1227
= 3 / 409
= 3
Step3:
LCM(1, 659) = 659
GCD(1, 659) = ( 1 x 659 ) / 659
= 1 / 659
= 1
So, Greatest Common Divisor of 210, 981, 409, 659 is 1
