GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(705, 847) = 597135
GCD(705, 847) = ( 705 x 847 ) / 597135
= 705 / 847
= 705
Step2:
LCM(1, 139) = 139
GCD(1, 139) = ( 1 x 139 ) / 139
= 1 / 139
= 1
Step3:
LCM(1, 678) = 678
GCD(1, 678) = ( 1 x 678 ) / 678
= 1 / 678
= 1
So, Greatest Common Divisor of 705, 847, 139, 678 is 1
