Given numbers are 279, 554, 639, 203
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(279, 554) = 154566
GCD(279, 554) = ( 279 x 554 ) / 154566
= 279 / 554
= 279
Step2:
LCM(1, 639) = 639
GCD(1, 639) = ( 1 x 639 ) / 639
= 1 / 639
= 1
Step3:
LCM(1, 203) = 203
GCD(1, 203) = ( 1 x 203 ) / 203
= 1 / 203
= 1
So, Greatest Common Divisor of 279, 554, 639, 203 is 1
