Given numbers are 405, 371, 249, 877
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(405, 371) = 150255
GCD(405, 371) = ( 405 x 371 ) / 150255
= 405 / 371
= 405
Step2:
LCM(1, 249) = 249
GCD(1, 249) = ( 1 x 249 ) / 249
= 1 / 249
= 1
Step3:
LCM(1, 877) = 877
GCD(1, 877) = ( 1 x 877 ) / 877
= 1 / 877
= 1
So, Greatest Common Divisor of 405, 371, 249, 877 is 1
