Given numbers are 409, 253, 393, 201
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(409, 253) = 103477
GCD(409, 253) = ( 409 x 253 ) / 103477
= 409 / 253
= 409
Step2:
LCM(1, 393) = 393
GCD(1, 393) = ( 1 x 393 ) / 393
= 1 / 393
= 1
Step3:
LCM(1, 201) = 201
GCD(1, 201) = ( 1 x 201 ) / 201
= 1 / 201
= 1
So, Greatest Common Divisor of 409, 253, 393, 201 is 1
