Given numbers are 678, 545, 247, 417
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(678, 545) = 369510
GCD(678, 545) = ( 678 x 545 ) / 369510
= 678 / 545
= 678
Step2:
LCM(1, 247) = 247
GCD(1, 247) = ( 1 x 247 ) / 247
= 1 / 247
= 1
Step3:
LCM(1, 417) = 417
GCD(1, 417) = ( 1 x 417 ) / 417
= 1 / 417
= 1
So, Greatest Common Divisor of 678, 545, 247, 417 is 1
