Given numbers are 362,420,838,767,465
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 362,420,838,767,465 is 757354039260.
Find LCM of 362,420,838,767,465 with Prime Factorization
| 2 | 362, 420, 838, 767, 465 |
| 3 | 181, 210, 419, 767, 465 |
| 5 | 181, 70, 419, 767, 155 |
| 181, 14, 419, 767, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 181 x 14 x 419 x 767 x 31 = 757354039260
Therefore, the lowest common multiple of 362,420,838,767,465 is 757354039260.
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.
362 x 420 x 838 x 767 x 465 = 45441242355600
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.
362 : 1, 2, 181, 362
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
838 : 1, 2, 419, 838
767 : 1, 13, 59, 767
465 : 1, 3, 5, 15, 31, 93, 155, 465
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 362,420,838,767,465, is 1.
Now, the common factors can be found like this.
362:2x 181
420:2x 2x 3x 5x 7
838:2x 419
767:13x 59
465:3x 5x 31
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 3x 5 = 60
Therefore, the value for common factors is 60.
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 = 45441242355600/(1x60)
LCM = 45441242355600/60
LCM = 757354039260
Thus, we can understand that the LCM of 362,420,838,767,465 is 757354039260.
