Given numbers are 545, 245, 942, 205
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(545, 245) = 26705
GCD(545, 245) = ( 545 x 245 ) / 26705
= 545 / 245
= 545
Step2:
LCM(5, 942) = 4710
GCD(5, 942) = ( 5 x 942 ) / 4710
= 5 / 942
= 5
Step3:
LCM(1, 205) = 205
GCD(1, 205) = ( 1 x 205 ) / 205
= 1 / 205
= 1
So, Greatest Common Divisor of 545, 245, 942, 205 is 1
