Given numbers are 643, 496, 381, 662
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(643, 496) = 318928
GCD(643, 496) = ( 643 x 496 ) / 318928
= 643 / 496
= 643
Step2:
LCM(1, 381) = 381
GCD(1, 381) = ( 1 x 381 ) / 381
= 1 / 381
= 1
Step3:
LCM(1, 662) = 662
GCD(1, 662) = ( 1 x 662 ) / 662
= 1 / 662
= 1
So, Greatest Common Divisor of 643, 496, 381, 662 is 1
