Given numbers are 972,769,883,642,749
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 972,769,883,642,749 is 494350668756.
Find LCM of 972,769,883,642,749 with Prime Factorization
| 2 | 972, 769, 883, 642, 749 |
| 3 | 486, 769, 883, 321, 749 |
| 107 | 162, 769, 883, 107, 749 |
| 162, 769, 883, 1, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 107 x 162 x 769 x 883 x 1 x 7 = 494350668756
Therefore, the lowest common multiple of 972,769,883,642,749 is 494350668756.
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.
972 x 769 x 883 x 642 x 749 = 317373129341352
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.
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
769 : 1, 769
883 : 1, 883
642 : 1, 2, 3, 6, 107, 214, 321, 642
749 : 1, 7, 107, 749
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 972,769,883,642,749, is 1.
Now, the common factors can be found like this.
972:2x 2x 3x 3x 3x 3x 3
769:769
883:883
642:2x 3x 107
749:7x 107
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 107 = 642
Therefore, the value for common factors is 642.
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 = 317373129341352/(1x642)
LCM = 317373129341352/642
LCM = 494350668756
Thus, we can understand that the LCM of 972,769,883,642,749 is 494350668756.
