Find LCM of 473,690,619,644,860 with Prime Factorization
| 2 | 473, 690, 619, 644, 860 |
| 2 | 473, 345, 619, 322, 430 |
| 5 | 473, 345, 619, 161, 215 |
| 23 | 473, 69, 619, 161, 43 |
| 43 | 473, 3, 619, 7, 43 |
| 11, 3, 619, 7, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 23 x 43 x 11 x 3 x 619 x 7 x 1 = 2828322420
Therefore, the lowest common multiple of 473,690,619,644,860 is 2828322420.
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.
473 x 690 x 619 x 644 x 860 = 111888434935200
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.
473 : 1, 11, 43, 473
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
619 : 1, 619
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 473,690,619,644,860, is 1.
Now, the common factors can be found like this.
473:11x 43
690:2x 3x 5x 23
619:619
644:2x 2x 7x 23
860:2x 2x 5x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 5x 23x 43 = 39560
Therefore, the value for common factors is 39560.
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 = 111888434935200/(1x39560)
LCM = 111888434935200/39560
LCM = 2828322420
Thus, we can understand that the LCM of 473,690,619,644,860 is 2828322420.
