Given numbers are 437,420,886,322
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 437,420,886,322 is 81308220.
Find LCM of 437,420,886,322 with Prime Factorization
| 2 | 437, 420, 886, 322 |
| 7 | 437, 210, 443, 161 |
| 23 | 437, 30, 443, 23 |
| 19, 30, 443, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 23 x 19 x 30 x 443 x 1 = 81308220
Therefore, the lowest common multiple of 437,420,886,322 is 81308220.
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.
437 x 420 x 886 x 322 = 52362493680
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.
437 : 1, 19, 23, 437
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
886 : 1, 2, 443, 886
322 : 1, 2, 7, 14, 23, 46, 161, 322
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 437,420,886,322, is 1.
Now, the common factors can be found like this.
437:19x 23
420:2x 2x 3x 5x 7
886:2x 443
322:2x 7x 23
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 23 = 644
Therefore, the value for common factors is 644.
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 = 52362493680/(1x644)
LCM = 52362493680/644
LCM = 81308220
Thus, we can understand that the LCM of 437,420,886,322 is 81308220.
