Find LCM of 813,583,151,735,420 with Prime Factorization
| 3 | 813, 583, 151, 735, 420 |
| 5 | 271, 583, 151, 245, 140 |
| 7 | 271, 583, 151, 49, 28 |
| 271, 583, 151, 7, 4 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 7 x 271 x 583 x 151 x 7 x 4 = 70139412420
Therefore, the lowest common multiple of 813,583,151,735,420 is 70139412420.
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.
813 x 583 x 151 x 735 x 420 = 22093914912300
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.
813 : 1, 3, 271, 813
583 : 1, 11, 53, 583
151 : 1, 151
735 : 1, 3, 5, 7, 15, 21, 35, 49, 105, 147, 245, 735
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 813,583,151,735,420, is 1.
Now, the common factors can be found like this.
813:3x 271
583:11x 53
151:151
735:3x 5x 7x 7
420:2x 2x 3x 5x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 5x 7 = 315
Therefore, the value for common factors is 315.
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 = 22093914912300/(1x315)
LCM = 22093914912300/315
LCM = 70139412420
Thus, we can understand that the LCM of 813,583,151,735,420 is 70139412420.
