Find LCM of 974,440,858,619,487 with Prime Factorization
2 | 974, 440, 858, 619, 487 |
11 | 487, 220, 429, 619, 487 |
487 | 487, 20, 39, 619, 487 |
1, 20, 39, 619, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 487 x 1 x 20 x 39 x 619 x 1 = 5172933480
Therefore, the lowest common multiple of 974,440,858,619,487 is 5172933480.
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.
974 x 440 x 858 x 619 x 487 = 110845618609440
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.
974 : 1, 2, 487, 974
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
619 : 1, 619
487 : 1, 487
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 974,440,858,619,487, is 1.
Now, the common factors can be found like this.
974:2x 487
440:2x 2x 2x 5x 11
858:2x 3x 11x 13
619:619
487:487
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 11x 487 = 21428
Therefore, the value for common factors is 21428.
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 = 110845618609440/(1x21428)
LCM = 110845618609440/21428
LCM = 5172933480
Thus, we can understand that the LCM of 974,440,858,619,487 is 5172933480.
