Given numbers are 646,755,437,953
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 646,755,437,953 is 10690553870.
Find LCM of 646,755,437,953 with Prime Factorization
| 19 | 646, 755, 437, 953 |
| 34, 755, 23, 953 |
Multiply the prime numbers at the bottom and the left side.
19 x 34 x 755 x 23 x 953 = 10690553870
Therefore, the lowest common multiple of 646,755,437,953 is 10690553870.
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.
646 x 755 x 437 x 953 = 203120523530
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.
646 : 1, 2, 17, 19, 34, 38, 323, 646
755 : 1, 5, 151, 755
437 : 1, 19, 23, 437
953 : 1, 953
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,755,437,953, is 1.
Now, the common factors can be found like this.
646:2x 17x 19
755:5x 151
437:19x 23
953:953
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
19 = 19
Therefore, the value for common factors is 19.
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 = 203120523530/(1x19)
LCM = 203120523530/19
LCM = 10690553870
Thus, we can understand that the LCM of 646,755,437,953 is 10690553870.
