Given numbers are 493,646,354,762
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 493,646,354,762 is 421121586.
Find LCM of 493,646,354,762 with Prime Factorization
| 2 | 493, 646, 354, 762 |
| 3 | 493, 323, 177, 381 |
| 17 | 493, 323, 59, 127 |
| 29, 19, 59, 127 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 17 x 29 x 19 x 59 x 127 = 421121586
Therefore, the lowest common multiple of 493,646,354,762 is 421121586.
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.
493 x 646 x 354 x 762 = 85908803544
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.
493 : 1, 17, 29, 493
646 : 1, 2, 17, 19, 34, 38, 323, 646
354 : 1, 2, 3, 6, 59, 118, 177, 354
762 : 1, 2, 3, 6, 127, 254, 381, 762
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 493,646,354,762, is 1.
Now, the common factors can be found like this.
493:17x 29
646:2x 17x 19
354:2x 3x 59
762:2x 3x 127
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 17 = 204
Therefore, the value for common factors is 204.
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 = 85908803544/(1x204)
LCM = 85908803544/204
LCM = 421121586
Thus, we can understand that the LCM of 493,646,354,762 is 421121586.
