The LCM of 971,930,540,621 is 373854420.
Find LCM of 971,930,540,621 with Prime Factorization
| 2 | 971, 930, 540, 621 |
| 3 | 971, 465, 270, 621 |
| 3 | 971, 155, 90, 207 |
| 3 | 971, 155, 30, 69 |
| 5 | 971, 155, 10, 23 |
| 971, 31, 2, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 5 x 971 x 31 x 2 x 23 = 373854420
Therefore, the lowest common multiple of 971,930,540,621 is 373854420.
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.
971 x 930 x 540 x 621 = 302822080200
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.
971 : 1, 971
930 : 1, 2, 3, 5, 6, 10, 15, 30, 31, 62, 93, 155, 186, 310, 465, 930
540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540
621 : 1, 3, 9, 23, 27, 69, 207, 621
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 971,930,540,621, is 1.
Now, the common factors can be found like this.
971:971
930:2x 3x 5x 31
540:2x 2x 3x 3x 3x 5
621:3x 3x 3x 23
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 3x 3x 3x 5 = 810
Therefore, the value for common factors is 810.
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 = 302822080200/(1x810)
LCM = 302822080200/810
LCM = 373854420
Thus, we can understand that the LCM of 971,930,540,621 is 373854420.
