Given numbers are 278, 538, 831, 940
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(278, 538) = 74782
GCD(278, 538) = ( 278 x 538 ) / 74782
= 278 / 538
= 278
Step2:
LCM(2, 831) = 1662
GCD(2, 831) = ( 2 x 831 ) / 1662
= 2 / 831
= 2
Step3:
LCM(1, 940) = 940
GCD(1, 940) = ( 1 x 940 ) / 940
= 1 / 940
= 1
So, Greatest Common Divisor of 278, 538, 831, 940 is 1
