Given numbers are 356,217,781,994
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 356,217,781,994 is 60333812.
Find LCM of 356,217,781,994 with Prime Factorization
| 2 | 356, 217, 781, 994 |
| 7 | 178, 217, 781, 497 |
| 71 | 178, 31, 781, 71 |
| 178, 31, 11, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 71 x 178 x 31 x 11 x 1 = 60333812
Therefore, the lowest common multiple of 356,217,781,994 is 60333812.
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 217 x 781 x 994 = 59971809128
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
217 : 1, 7, 31, 217
781 : 1, 11, 71, 781
994 : 1, 2, 7, 14, 71, 142, 497, 994
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 356,217,781,994, is 1.
Now, the common factors can be found like this.
356:2x 2x 89
217:7x 31
781:11x 71
994:2x 7x 71
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 71 = 994
Therefore, the value for common factors is 994.
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 = 59971809128/(1x994)
LCM = 59971809128/994
LCM = 60333812
Thus, we can understand that the LCM of 356,217,781,994 is 60333812.
