Given numbers are 658,340,771,376
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 658,340,771,376 is 172488120.
Find LCM of 658,340,771,376 with Prime Factorization
2 | 658, 340, 771, 376 |
2 | 329, 170, 771, 188 |
47 | 329, 85, 771, 94 |
7, 85, 771, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 47 x 7 x 85 x 771 x 2 = 172488120
Therefore, the lowest common multiple of 658,340,771,376 is 172488120.
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.
658 x 340 x 771 x 376 = 64855533120
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.
658 : 1, 2, 7, 14, 47, 94, 329, 658
340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340
771 : 1, 3, 257, 771
376 : 1, 2, 4, 8, 47, 94, 188, 376
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 658,340,771,376, is 1.
Now, the common factors can be found like this.
658:2x 7x 47
340:2x 2x 5x 17
771:3x 257
376:2x 2x 2x 47
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 47 = 376
Therefore, the value for common factors is 376.
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 = 64855533120/(1x376)
LCM = 64855533120/376
LCM = 172488120
Thus, we can understand that the LCM of 658,340,771,376 is 172488120.
