Given numbers are 751,740,543,862,905
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 751,740,543,862,905 is 130061499420.
Find LCM of 751,740,543,862,905 with Prime Factorization
| 2 | 751, 740, 543, 862, 905 |
| 5 | 751, 370, 543, 431, 905 |
| 181 | 751, 74, 543, 431, 181 |
| 751, 74, 3, 431, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 181 x 751 x 74 x 3 x 431 x 1 = 130061499420
Therefore, the lowest common multiple of 751,740,543,862,905 is 130061499420.
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.
751 x 740 x 543 x 862 x 905 = 235411313950200
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.
751 : 1, 751
740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740
543 : 1, 3, 181, 543
862 : 1, 2, 431, 862
905 : 1, 5, 181, 905
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 751,740,543,862,905, is 1.
Now, the common factors can be found like this.
751:751
740:2x 2x 5x 37
543:3x 181
862:2x 431
905:5x 181
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 181 = 1810
Therefore, the value for common factors is 1810.
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 = 235411313950200/(1x1810)
LCM = 235411313950200/1810
LCM = 130061499420
Thus, we can understand that the LCM of 751,740,543,862,905 is 130061499420.
