Given numbers are 643, 178, 799, 133
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(643, 178) = 114454
GCD(643, 178) = ( 643 x 178 ) / 114454
= 643 / 178
= 643
Step2:
LCM(1, 799) = 799
GCD(1, 799) = ( 1 x 799 ) / 799
= 1 / 799
= 1
Step3:
LCM(1, 133) = 133
GCD(1, 133) = ( 1 x 133 ) / 133
= 1 / 133
= 1
So, Greatest Common Divisor of 643, 178, 799, 133 is 1
