Given numbers are 705, 209, 703, 278
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(705, 209) = 147345
GCD(705, 209) = ( 705 x 209 ) / 147345
= 705 / 209
= 705
Step2:
LCM(1, 703) = 703
GCD(1, 703) = ( 1 x 703 ) / 703
= 1 / 703
= 1
Step3:
LCM(1, 278) = 278
GCD(1, 278) = ( 1 x 278 ) / 278
= 1 / 278
= 1
So, Greatest Common Divisor of 705, 209, 703, 278 is 1
