Given numbers are 249, 980, 546, 843
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(249, 980) = 244020
GCD(249, 980) = ( 249 x 980 ) / 244020
= 249 / 980
= 249
Step2:
LCM(1, 546) = 546
GCD(1, 546) = ( 1 x 546 ) / 546
= 1 / 546
= 1
Step3:
LCM(1, 843) = 843
GCD(1, 843) = ( 1 x 843 ) / 843
= 1 / 843
= 1
So, Greatest Common Divisor of 249, 980, 546, 843 is 1
