Given numbers are 470, 266, 391, 623
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(470, 266) = 62510
GCD(470, 266) = ( 470 x 266 ) / 62510
= 470 / 266
= 470
Step2:
LCM(2, 391) = 782
GCD(2, 391) = ( 2 x 391 ) / 782
= 2 / 391
= 2
Step3:
LCM(1, 623) = 623
GCD(1, 623) = ( 1 x 623 ) / 623
= 1 / 623
= 1
So, Greatest Common Divisor of 470, 266, 391, 623 is 1
