Given numbers are 398,695,630,533,974
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 398,695,630,533,974 is 4523395861530.
Find LCM of 398,695,630,533,974 with Prime Factorization
2 | 398, 695, 630, 533, 974 |
5 | 199, 695, 315, 533, 487 |
199, 139, 63, 533, 487 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 199 x 139 x 63 x 533 x 487 = 4523395861530
Therefore, the lowest common multiple of 398,695,630,533,974 is 4523395861530.
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.
398 x 695 x 630 x 533 x 974 = 90467917230600
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.
398 : 1, 2, 199, 398
695 : 1, 5, 139, 695
630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630
533 : 1, 13, 41, 533
974 : 1, 2, 487, 974
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,695,630,533,974, is 1.
Now, the common factors can be found like this.
398:2x 199
695:5x 139
630:2x 3x 3x 5x 7
533:13x 41
974:2x 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 5 = 20
Therefore, the value for common factors is 20.
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 = 90467917230600/(1x20)
LCM = 90467917230600/20
LCM = 4523395861530
Thus, we can understand that the LCM of 398,695,630,533,974 is 4523395861530.
