Given numbers are 778,961,533,894
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 778,961,533,894 is 178130266158.
Find LCM of 778,961,533,894 with Prime Factorization
| 2 | 778, 961, 533, 894 |
| 389, 961, 533, 447 |
Multiply the prime numbers at the bottom and the left side.
2 x 389 x 961 x 533 x 447 = 178130266158
Therefore, the lowest common multiple of 778,961,533,894 is 178130266158.
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.
778 x 961 x 533 x 894 = 356260532316
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.
778 : 1, 2, 389, 778
961 : 1, 31, 961
533 : 1, 13, 41, 533
894 : 1, 2, 3, 6, 149, 298, 447, 894
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 778,961,533,894, is 1.
Now, the common factors can be found like this.
778:2x 389
961:31x 31
533:13x 41
894:2x 3x 149
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 = 356260532316/(1x2)
LCM = 356260532316/2
LCM = 178130266158
Thus, we can understand that the LCM of 778,961,533,894 is 178130266158.
