Given numbers are 251,441,641,402
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 251,441,641,402 is 9507692754.
Find LCM of 251,441,641,402 with Prime Factorization
3 | 251, 441, 641, 402 |
251, 147, 641, 134 |
Multiply the prime numbers at the bottom and the left side.
3 x 251 x 147 x 641 x 134 = 9507692754
Therefore, the lowest common multiple of 251,441,641,402 is 9507692754.
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.
251 x 441 x 641 x 402 = 28523078262
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.
251 : 1, 251
441 : 1, 3, 7, 9, 21, 49, 63, 147, 441
641 : 1, 641
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 251,441,641,402, is 1.
Now, the common factors can be found like this.
251:251
441:3x 3x 7x 7
641:641
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.
3 = 3
Therefore, the value for common factors is 3.
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 = 28523078262/(1x3)
LCM = 28523078262/3
LCM = 9507692754
Thus, we can understand that the LCM of 251,441,641,402 is 9507692754.
