Find LCM of 553,530,155,795,630 with Prime Factorization
| 2 | 553, 530, 155, 795, 630 |
| 3 | 553, 265, 155, 795, 315 |
| 5 | 553, 265, 155, 265, 105 |
| 7 | 553, 53, 31, 53, 21 |
| 53 | 79, 53, 31, 53, 3 |
| 79, 1, 31, 1, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 53 x 79 x 1 x 31 x 1 x 3 = 81772110
Therefore, the lowest common multiple of 553,530,155,795,630 is 81772110.
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.
553 x 530 x 155 x 795 x 630 = 22753089607500
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.
553 : 1, 7, 79, 553
530 : 1, 2, 5, 10, 53, 106, 265, 530
155 : 1, 5, 31, 155
795 : 1, 3, 5, 15, 53, 159, 265, 795
630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 553,530,155,795,630, is 1.
Now, the common factors can be found like this.
553:7x 79
530:2x 5x 53
155:5x 31
795:3x 5x 53
630:2x 3x 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.
2x 3x 5x 5x 5x 7x 53 = 278250
Therefore, the value for common factors is 278250.
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 = 22753089607500/(1x278250)
LCM = 22753089607500/278250
LCM = 81772110
Thus, we can understand that the LCM of 553,530,155,795,630 is 81772110.
