Given numbers are 749,106,364,286,947
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 749,106,364,286,947 is 21503229748.
Find LCM of 749,106,364,286,947 with Prime Factorization
| 2 | 749, 106, 364, 286, 947 |
| 7 | 749, 53, 182, 143, 947 |
| 13 | 107, 53, 26, 143, 947 |
| 107, 53, 2, 11, 947 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 13 x 107 x 53 x 2 x 11 x 947 = 21503229748
Therefore, the lowest common multiple of 749,106,364,286,947 is 21503229748.
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.
749 x 106 x 364 x 286 x 947 = 7827175628272
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.
749 : 1, 7, 107, 749
106 : 1, 2, 53, 106
364 : 1, 2, 4, 7, 13, 14, 26, 28, 52, 91, 182, 364
286 : 1, 2, 11, 13, 22, 26, 143, 286
947 : 1, 947
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 749,106,364,286,947, is 1.
Now, the common factors can be found like this.
749:7x 107
106:2x 53
364:2x 2x 7x 13
286:2x 11x 13
947:947
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 7x 13 = 364
Therefore, the value for common factors is 364.
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 = 7827175628272/(1x364)
LCM = 7827175628272/364
LCM = 21503229748
Thus, we can understand that the LCM of 749,106,364,286,947 is 21503229748.
