Given numbers are 917,971,242,770
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 917,971,242,770 is 1077392470.
Find LCM of 917,971,242,770 with Prime Factorization
| 2 | 917, 971, 242, 770 |
| 7 | 917, 971, 121, 385 |
| 11 | 131, 971, 121, 55 |
| 131, 971, 11, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 11 x 131 x 971 x 11 x 5 = 1077392470
Therefore, the lowest common multiple of 917,971,242,770 is 1077392470.
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.
917 x 971 x 242 x 770 = 165918440380
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.
917 : 1, 7, 131, 917
971 : 1, 971
242 : 1, 2, 11, 22, 121, 242
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 917,971,242,770, is 1.
Now, the common factors can be found like this.
917:7x 131
971:971
242:2x 11x 11
770:2x 5x 7x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 11 = 154
Therefore, the value for common factors is 154.
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 = 165918440380/(1x154)
LCM = 165918440380/154
LCM = 1077392470
Thus, we can understand that the LCM of 917,971,242,770 is 1077392470.
