Given numbers are 643,619,708,441,352
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 643,619,708,441,352 is 3645313521696.
Find LCM of 643,619,708,441,352 with Prime Factorization
2 | 643, 619, 708, 441, 352 |
2 | 643, 619, 354, 441, 176 |
3 | 643, 619, 177, 441, 88 |
643, 619, 59, 147, 88 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 643 x 619 x 59 x 147 x 88 = 3645313521696
Therefore, the lowest common multiple of 643,619,708,441,352 is 3645313521696.
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.
643 x 619 x 708 x 441 x 352 = 43743762260352
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.
643 : 1, 643
619 : 1, 619
708 : 1, 2, 3, 4, 6, 12, 59, 118, 177, 236, 354, 708
441 : 1, 3, 7, 9, 21, 49, 63, 147, 441
352 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 88, 176, 352
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 643,619,708,441,352, is 1.
Now, the common factors can be found like this.
643:643
619:619
708:2x 2x 3x 59
441:3x 3x 7x 7
352:2x 2x 2x 2x 2x 11
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 3 = 12
Therefore, the value for common factors is 12.
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 = 43743762260352/(1x12)
LCM = 43743762260352/12
LCM = 3645313521696
Thus, we can understand that the LCM of 643,619,708,441,352 is 3645313521696.
