Given numbers are 191, 438, 278, 890
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(191, 438) = 83658
GCD(191, 438) = ( 191 x 438 ) / 83658
= 191 / 438
= 191
Step2:
LCM(1, 278) = 278
GCD(1, 278) = ( 1 x 278 ) / 278
= 1 / 278
= 1
Step3:
LCM(1, 890) = 890
GCD(1, 890) = ( 1 x 890 ) / 890
= 1 / 890
= 1
So, Greatest Common Divisor of 191, 438, 278, 890 is 1
