Given numbers are 762,238,865,889
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 762,238,865,889 is 78436470.
Find LCM of 762,238,865,889 with Prime Factorization
2 | 762, 238, 865, 889 |
7 | 381, 119, 865, 889 |
127 | 381, 17, 865, 127 |
3, 17, 865, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 127 x 3 x 17 x 865 x 1 = 78436470
Therefore, the lowest common multiple of 762,238,865,889 is 78436470.
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.
762 x 238 x 865 x 889 = 139460043660
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.
762 : 1, 2, 3, 6, 127, 254, 381, 762
238 : 1, 2, 7, 14, 17, 34, 119, 238
865 : 1, 5, 173, 865
889 : 1, 7, 127, 889
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 762,238,865,889, is 1.
Now, the common factors can be found like this.
762:2x 3x 127
238:2x 7x 17
865:5x 173
889:7x 127
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 127 = 1778
Therefore, the value for common factors is 1778.
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 = 139460043660/(1x1778)
LCM = 139460043660/1778
LCM = 78436470
Thus, we can understand that the LCM of 762,238,865,889 is 78436470.
