Given numbers are 185, 164, 643, 647
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(185, 164) = 30340
GCD(185, 164) = ( 185 x 164 ) / 30340
= 185 / 164
= 185
Step2:
LCM(1, 643) = 643
GCD(1, 643) = ( 1 x 643 ) / 643
= 1 / 643
= 1
Step3:
LCM(1, 647) = 647
GCD(1, 647) = ( 1 x 647 ) / 647
= 1 / 647
= 1
So, Greatest Common Divisor of 185, 164, 643, 647 is 1
