Given numbers are 642,175,787,834
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 642,175,787,834 is 12290303550.
Find LCM of 642,175,787,834 with Prime Factorization
2 | 642, 175, 787, 834 |
3 | 321, 175, 787, 417 |
107, 175, 787, 139 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 107 x 175 x 787 x 139 = 12290303550
Therefore, the lowest common multiple of 642,175,787,834 is 12290303550.
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.
642 x 175 x 787 x 834 = 73741821300
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.
642 : 1, 2, 3, 6, 107, 214, 321, 642
175 : 1, 5, 7, 25, 35, 175
787 : 1, 787
834 : 1, 2, 3, 6, 139, 278, 417, 834
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,175,787,834, is 1.
Now, the common factors can be found like this.
642:2x 3x 107
175:5x 5x 7
787:787
834:2x 3x 139
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3 = 6
Therefore, the value for common factors is 6.
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 = 73741821300/(1x6)
LCM = 73741821300/6
LCM = 12290303550
Thus, we can understand that the LCM of 642,175,787,834 is 12290303550.
