Given numbers are 356,889,169,770
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 356,889,169,770 is 2941718780.
Find LCM of 356,889,169,770 with Prime Factorization
| 2 | 356, 889, 169, 770 |
| 7 | 178, 889, 169, 385 |
| 178, 127, 169, 55 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 178 x 127 x 169 x 55 = 2941718780
Therefore, the lowest common multiple of 356,889,169,770 is 2941718780.
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.
356 x 889 x 169 x 770 = 41184062920
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.
356 : 1, 2, 4, 89, 178, 356
889 : 1, 7, 127, 889
169 : 1, 13, 169
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 356,889,169,770, is 1.
Now, the common factors can be found like this.
356:2x 2x 89
889:7x 127
169:13x 13
770:2x 5x 7x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7 = 14
Therefore, the value for common factors is 14.
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 = 41184062920/(1x14)
LCM = 41184062920/14
LCM = 2941718780
Thus, we can understand that the LCM of 356,889,169,770 is 2941718780.
