Given numbers are 751,813,402,402
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 751,813,402,402 is 81815442.
Find LCM of 751,813,402,402 with Prime Factorization
| 2 | 751, 813, 402, 402 |
| 3 | 751, 813, 201, 201 |
| 67 | 751, 271, 67, 67 |
| 751, 271, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 67 x 751 x 271 x 1 x 1 = 81815442
Therefore, the lowest common multiple of 751,813,402,402 is 81815442.
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.
751 x 813 x 402 x 402 = 98669423052
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.
751 : 1, 751
813 : 1, 3, 271, 813
402 : 1, 2, 3, 6, 67, 134, 201, 402
402 : 1, 2, 3, 6, 67, 134, 201, 402
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 751,813,402,402, is 1.
Now, the common factors can be found like this.
751:751
813:3x 271
402:2x 3x 67
402:2x 3x 67
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 67 = 1206
Therefore, the value for common factors is 1206.
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 = 98669423052/(1x1206)
LCM = 98669423052/1206
LCM = 81815442
Thus, we can understand that the LCM of 751,813,402,402 is 81815442.
