Given numbers are 917, 705, 129, 763
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(917, 705) = 646485
GCD(917, 705) = ( 917 x 705 ) / 646485
= 917 / 705
= 917
Step2:
LCM(1, 129) = 129
GCD(1, 129) = ( 1 x 129 ) / 129
= 1 / 129
= 1
Step3:
LCM(1, 763) = 763
GCD(1, 763) = ( 1 x 763 ) / 763
= 1 / 763
= 1
So, Greatest Common Divisor of 917, 705, 129, 763 is 1
