Given numbers are 278, 531, 863, 242
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(278, 531) = 147618
GCD(278, 531) = ( 278 x 531 ) / 147618
= 278 / 531
= 278
Step2:
LCM(1, 863) = 863
GCD(1, 863) = ( 1 x 863 ) / 863
= 1 / 863
= 1
Step3:
LCM(1, 242) = 242
GCD(1, 242) = ( 1 x 242 ) / 242
= 1 / 242
= 1
So, Greatest Common Divisor of 278, 531, 863, 242 is 1
