Given numbers are 651,443,840,228
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 651,443,840,228 is 219178680.
Find LCM of 651,443,840,228 with Prime Factorization
| 2 | 651, 443, 840, 228 |
| 2 | 651, 443, 420, 114 |
| 3 | 651, 443, 210, 57 |
| 7 | 217, 443, 70, 19 |
| 31, 443, 10, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 31 x 443 x 10 x 19 = 219178680
Therefore, the lowest common multiple of 651,443,840,228 is 219178680.
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.
651 x 443 x 840 x 228 = 55233027360
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.
651 : 1, 3, 7, 21, 31, 93, 217, 651
443 : 1, 443
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
228 : 1, 2, 3, 4, 6, 12, 19, 38, 57, 76, 114, 228
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 651,443,840,228, is 1.
Now, the common factors can be found like this.
651:3x 7x 31
443:443
840:2x 2x 2x 3x 5x 7
228:2x 2x 3x 19
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 3x 3x 7 = 252
Therefore, the value for common factors is 252.
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 = 55233027360/(1x252)
LCM = 55233027360/252
LCM = 219178680
Thus, we can understand that the LCM of 651,443,840,228 is 219178680.
