Given numbers are 163, 284, 745, 172
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(163, 284) = 46292
GCD(163, 284) = ( 163 x 284 ) / 46292
= 163 / 284
= 163
Step2:
LCM(1, 745) = 745
GCD(1, 745) = ( 1 x 745 ) / 745
= 1 / 745
= 1
Step3:
LCM(1, 172) = 172
GCD(1, 172) = ( 1 x 172 ) / 172
= 1 / 172
= 1
So, Greatest Common Divisor of 163, 284, 745, 172 is 1
