Given numbers are 684, 163, 172, 786
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(684, 163) = 111492
GCD(684, 163) = ( 684 x 163 ) / 111492
= 684 / 163
= 684
Step2:
LCM(1, 172) = 172
GCD(1, 172) = ( 1 x 172 ) / 172
= 1 / 172
= 1
Step3:
LCM(1, 786) = 786
GCD(1, 786) = ( 1 x 786 ) / 786
= 1 / 786
= 1
So, Greatest Common Divisor of 684, 163, 172, 786 is 1
