Given numbers are 753,308,994,639
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 753,308,994,639 is 49399812.
Find LCM of 753,308,994,639 with Prime Factorization
2 | 753, 308, 994, 639 |
3 | 753, 154, 497, 639 |
7 | 251, 154, 497, 213 |
71 | 251, 22, 71, 213 |
251, 22, 1, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 71 x 251 x 22 x 1 x 3 = 49399812
Therefore, the lowest common multiple of 753,308,994,639 is 49399812.
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.
753 x 308 x 994 x 639 = 147310239384
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.
753 : 1, 3, 251, 753
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
994 : 1, 2, 7, 14, 71, 142, 497, 994
639 : 1, 3, 9, 71, 213, 639
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 753,308,994,639, is 1.
Now, the common factors can be found like this.
753:3x 251
308:2x 2x 7x 11
994:2x 7x 71
639:3x 3x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 7x 71 = 2982
Therefore, the value for common factors is 2982.
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 = 147310239384/(1x2982)
LCM = 147310239384/2982
LCM = 49399812
Thus, we can understand that the LCM of 753,308,994,639 is 49399812.
