Find LCM of 455,978,819,358,619 with Prime Factorization
| 2 | 455, 978, 819, 358, 619 |
| 3 | 455, 489, 819, 179, 619 |
| 7 | 455, 163, 273, 179, 619 |
| 13 | 65, 163, 39, 179, 619 |
| 5, 163, 3, 179, 619 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 13 x 5 x 163 x 3 x 179 x 619 = 147916010970
Therefore, the lowest common multiple of 455,978,819,358,619 is 147916010970.
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.
455 x 978 x 819 x 358 x 619 = 80762141989620
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.
455 : 1, 5, 7, 13, 35, 65, 91, 455
978 : 1, 2, 3, 6, 163, 326, 489, 978
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
358 : 1, 2, 179, 358
619 : 1, 619
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 455,978,819,358,619, is 1.
Now, the common factors can be found like this.
455:5x 7x 13
978:2x 3x 163
819:3x 3x 7x 13
358:2x 179
619:619
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 13 = 546
Therefore, the value for common factors is 546.
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 = 80762141989620/(1x546)
LCM = 80762141989620/546
LCM = 147916010970
Thus, we can understand that the LCM of 455,978,819,358,619 is 147916010970.
