Given numbers are 278, 286, 470, 993
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(278, 286) = 39754
GCD(278, 286) = ( 278 x 286 ) / 39754
= 278 / 286
= 278
Step2:
LCM(2, 470) = 470
GCD(2, 470) = ( 2 x 470 ) / 470
= 2 / 470
= 2
Step3:
LCM(2, 993) = 1986
GCD(2, 993) = ( 2 x 993 ) / 1986
= 2 / 993
= 2
So, Greatest Common Divisor of 278, 286, 470, 993 is 1
