Given numbers are 814,769,989,124
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 814,769,989,124 is 38382983188.
Find LCM of 814,769,989,124 with Prime Factorization
2 | 814, 769, 989, 124 |
407, 769, 989, 62 |
Multiply the prime numbers at the bottom and the left side.
2 x 407 x 769 x 989 x 62 = 38382983188
Therefore, the lowest common multiple of 814,769,989,124 is 38382983188.
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.
814 x 769 x 989 x 124 = 76765966376
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.
814 : 1, 2, 11, 22, 37, 74, 407, 814
769 : 1, 769
989 : 1, 23, 43, 989
124 : 1, 2, 4, 31, 62, 124
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 814,769,989,124, is 1.
Now, the common factors can be found like this.
814:2x 11x 37
769:769
989:23x 43
124:2x 2x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 76765966376/(1x2)
LCM = 76765966376/2
LCM = 38382983188
Thus, we can understand that the LCM of 814,769,989,124 is 38382983188.
