Given numbers are 642,986,452,942,901
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 642,986,452,942,901 is 595204092276.
Find LCM of 642,986,452,942,901 with Prime Factorization
2 | 642, 986, 452, 942, 901 |
3 | 321, 493, 226, 471, 901 |
17 | 107, 493, 226, 157, 901 |
107, 29, 226, 157, 53 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 17 x 107 x 29 x 226 x 157 x 53 = 595204092276
Therefore, the lowest common multiple of 642,986,452,942,901 is 595204092276.
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.
642 x 986 x 452 x 942 x 901 = 242843269648608
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.
642 : 1, 2, 3, 6, 107, 214, 321, 642
986 : 1, 2, 17, 29, 34, 58, 493, 986
452 : 1, 2, 4, 113, 226, 452
942 : 1, 2, 3, 6, 157, 314, 471, 942
901 : 1, 17, 53, 901
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,986,452,942,901, is 1.
Now, the common factors can be found like this.
642:2x 3x 107
986:2x 17x 29
452:2x 2x 113
942:2x 3x 157
901:17x 53
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 3x 17 = 408
Therefore, the value for common factors is 408.
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 = 242843269648608/(1x408)
LCM = 242843269648608/408
LCM = 595204092276
Thus, we can understand that the LCM of 642,986,452,942,901 is 595204092276.
