Given numbers are 210, 618, 161, 201
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(210, 618) = 21630
GCD(210, 618) = ( 210 x 618 ) / 21630
= 210 / 618
= 210
Step2:
LCM(6, 161) = 966
GCD(6, 161) = ( 6 x 161 ) / 966
= 6 / 161
= 6
Step3:
LCM(1, 201) = 201
GCD(1, 201) = ( 1 x 201 ) / 201
= 1 / 201
= 1
So, Greatest Common Divisor of 210, 618, 161, 201 is 1
