Given numbers are 436,874,665,689,984
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 436,874,665,689,984 is 1130291078280.
Find LCM of 436,874,665,689,984 with Prime Factorization
| 2 | 436, 874, 665, 689, 984 |
| 2 | 218, 437, 665, 689, 492 |
| 19 | 109, 437, 665, 689, 246 |
| 109, 23, 35, 689, 246 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 19 x 109 x 23 x 35 x 689 x 246 = 1130291078280
Therefore, the lowest common multiple of 436,874,665,689,984 is 1130291078280.
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.
436 x 874 x 665 x 689 x 984 = 171804243898560
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.
436 : 1, 2, 4, 109, 218, 436
874 : 1, 2, 19, 23, 38, 46, 437, 874
665 : 1, 5, 7, 19, 35, 95, 133, 665
689 : 1, 13, 53, 689
984 : 1, 2, 3, 4, 6, 8, 12, 24, 41, 82, 123, 164, 246, 328, 492, 984
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 436,874,665,689,984, is 1.
Now, the common factors can be found like this.
436:2x 2x 109
874:2x 19x 23
665:5x 7x 19
689:13x 53
984:2x 2x 2x 3x 41
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 19 = 152
Therefore, the value for common factors is 152.
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 = 171804243898560/(1x152)
LCM = 171804243898560/152
LCM = 1130291078280
Thus, we can understand that the LCM of 436,874,665,689,984 is 1130291078280.
