Given numbers are 920,802,756,476
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 920,802,756,476 is 1185339960.
Find LCM of 920,802,756,476 with Prime Factorization
| 2 | 920, 802, 756, 476 |
| 2 | 460, 401, 378, 238 |
| 7 | 230, 401, 189, 119 |
| 230, 401, 27, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 230 x 401 x 27 x 17 = 1185339960
Therefore, the lowest common multiple of 920,802,756,476 is 1185339960.
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.
920 x 802 x 756 x 476 = 265516151040
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.
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
802 : 1, 2, 401, 802
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
476 : 1, 2, 4, 7, 14, 17, 28, 34, 68, 119, 238, 476
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 920,802,756,476, is 2.
Now, the common factors can be found like this.
920:2x 2x 2x 5x 23
802:2x 401
756:2x 2x 3x 3x 3x 7
476:2x 2x 7x 17
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 2x 2x 7 = 112
Therefore, the value for common factors is 112.
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 = 265516151040/(2x112)
LCM = 265516151040/224
LCM = 1185339960
Thus, we can understand that the LCM of 920,802,756,476 is 1185339960.
