Given numbers are 437,755,805,980
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 437,755,805,980 is 64667260.
Find LCM of 437,755,805,980 with Prime Factorization
| 5 | 437, 755, 805, 980 |
| 7 | 437, 151, 161, 196 |
| 23 | 437, 151, 23, 28 |
| 19, 151, 1, 28 |
Multiply the prime numbers at the bottom and the left side.
5 x 7 x 23 x 19 x 151 x 1 x 28 = 64667260
Therefore, the lowest common multiple of 437,755,805,980 is 64667260.
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.
437 x 755 x 805 x 980 = 260285721500
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.
437 : 1, 19, 23, 437
755 : 1, 5, 151, 755
805 : 1, 5, 7, 23, 35, 115, 161, 805
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 437,755,805,980, is 1.
Now, the common factors can be found like this.
437:19x 23
755:5x 151
805:5x 7x 23
980:2x 2x 5x 7x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 5x 7x 23 = 4025
Therefore, the value for common factors is 4025.
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 = 260285721500/(1x4025)
LCM = 260285721500/4025
LCM = 64667260
Thus, we can understand that the LCM of 437,755,805,980 is 64667260.
