Given numbers are 493, 841, 643, 438
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(493, 841) = 14297
GCD(493, 841) = ( 493 x 841 ) / 14297
= 493 / 841
= 493
Step2:
LCM(29, 643) = 18647
GCD(29, 643) = ( 29 x 643 ) / 18647
= 29 / 643
= 29
Step3:
LCM(1, 438) = 438
GCD(1, 438) = ( 1 x 438 ) / 438
= 1 / 438
= 1
So, Greatest Common Divisor of 493, 841, 643, 438 is 1
