Given numbers are 747,947,996,210
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 747,947,996,210 is 99037260.
Find LCM of 747,947,996,210 with Prime Factorization
| 2 | 747, 947, 996, 210 |
| 3 | 747, 947, 498, 105 |
| 83 | 249, 947, 166, 35 |
| 3, 947, 2, 35 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 83 x 3 x 947 x 2 x 35 = 99037260
Therefore, the lowest common multiple of 747,947,996,210 is 99037260.
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.
747 x 947 x 996 x 210 = 147961666440
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.
747 : 1, 3, 9, 83, 249, 747
947 : 1, 947
996 : 1, 2, 3, 4, 6, 12, 83, 166, 249, 332, 498, 996
210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 747,947,996,210, is 1.
Now, the common factors can be found like this.
747:3x 3x 83
947:947
996:2x 2x 3x 83
210:2x 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.
2x 3x 3x 83 = 1494
Therefore, the value for common factors is 1494.
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 = 147961666440/(1x1494)
LCM = 147961666440/1494
LCM = 99037260
Thus, we can understand that the LCM of 747,947,996,210 is 99037260.
