Given numbers are 991,143,327,710,921
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 991,143,327,710,921 is 10100762713470.
Find LCM of 991,143,327,710,921 with Prime Factorization
3 | 991, 143, 327, 710, 921 |
991, 143, 109, 710, 307 |
Multiply the prime numbers at the bottom and the left side.
3 x 991 x 143 x 109 x 710 x 307 = 10100762713470
Therefore, the lowest common multiple of 991,143,327,710,921 is 10100762713470.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
991 x 143 x 327 x 710 x 921 = 30302288140410
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
991 : 1, 991
143 : 1, 11, 13, 143
327 : 1, 3, 109, 327
710 : 1, 2, 5, 10, 71, 142, 355, 710
921 : 1, 3, 307, 921
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 991,143,327,710,921, is 1.
Now, the common factors can be found like this.
991:991
143:11x 13
327:3x 109
710:2x 5x 71
921:3x 307
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 30302288140410/(1x3)
LCM = 30302288140410/3
LCM = 10100762713470
Thus, we can understand that the LCM of 991,143,327,710,921 is 10100762713470.
