Find LCM of 644,434,174,341,719 with Prime Factorization
2 | 644, 434, 174, 341, 719 |
7 | 322, 217, 87, 341, 719 |
31 | 46, 31, 87, 341, 719 |
46, 1, 87, 11, 719 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 31 x 46 x 1 x 87 x 11 x 719 = 13736889012
Therefore, the lowest common multiple of 644,434,174,341,719 is 13736889012.
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.
644 x 434 x 174 x 341 x 719 = 11923619662416
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.
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
434 : 1, 2, 7, 14, 31, 62, 217, 434
174 : 1, 2, 3, 6, 29, 58, 87, 174
341 : 1, 11, 31, 341
719 : 1, 719
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 644,434,174,341,719, is 1.
Now, the common factors can be found like this.
644:2x 2x 7x 23
434:2x 7x 31
174:2x 3x 29
341:11x 31
719:719
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 7x 31 = 868
Therefore, the value for common factors is 868.
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 = 11923619662416/(1x868)
LCM = 11923619662416/868
LCM = 13736889012
Thus, we can understand that the LCM of 644,434,174,341,719 is 13736889012.
