Given numbers are 866,380,715,972,356
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 866,380,715,972,356 is 508866440940.
Find LCM of 866,380,715,972,356 with Prime Factorization
| 2 | 866, 380, 715, 972, 356 |
| 2 | 433, 190, 715, 486, 178 |
| 5 | 433, 95, 715, 243, 89 |
| 433, 19, 143, 243, 89 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 433 x 19 x 143 x 243 x 89 = 508866440940
Therefore, the lowest common multiple of 866,380,715,972,356 is 508866440940.
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.
866 x 380 x 715 x 972 x 356 = 81418630550400
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.
866 : 1, 2, 433, 866
380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380
715 : 1, 5, 11, 13, 55, 65, 143, 715
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
356 : 1, 2, 4, 89, 178, 356
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 866,380,715,972,356, is 1.
Now, the common factors can be found like this.
866:2x 433
380:2x 2x 5x 19
715:5x 11x 13
972:2x 2x 3x 3x 3x 3x 3
356:2x 2x 89
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 2x 2x 5 = 160
Therefore, the value for common factors is 160.
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 = 81418630550400/(1x160)
LCM = 81418630550400/160
LCM = 508866440940
Thus, we can understand that the LCM of 866,380,715,972,356 is 508866440940.
