Given numbers are 361, 420, 251, 361
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(361, 420) = 151620
GCD(361, 420) = ( 361 x 420 ) / 151620
= 361 / 420
= 361
Step2:
LCM(1, 251) = 251
GCD(1, 251) = ( 1 x 251 ) / 251
= 1 / 251
= 1
Step3:
LCM(1, 361) = 361
GCD(1, 361) = ( 1 x 361 ) / 361
= 1 / 361
= 1
So, Greatest Common Divisor of 361, 420, 251, 361 is 1
