The LCM of 248,587,490,630 is 320995080.
Find LCM of 248,587,490,630 with Prime Factorization
| 2 | 248, 587, 490, 630 |
| 5 | 124, 587, 245, 315 |
| 7 | 124, 587, 49, 63 |
| 124, 587, 7, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 124 x 587 x 7 x 9 = 320995080
Therefore, the lowest common multiple of 248,587,490,630 is 320995080.
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.
248 x 587 x 490 x 630 = 44939311200
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.
248 : 1, 2, 4, 8, 31, 62, 124, 248
587 : 1, 587
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
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
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 248,587,490,630, is 1.
Now, the common factors can be found like this.
248:2x 2x 2x 31
587:587
490:2x 5x 7x 7
630:2x 3x 3x 5x 7
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 5x 7 = 140
Therefore, the value for common factors is 140.
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 = 44939311200/(1x140)
LCM = 44939311200/140
LCM = 320995080
Thus, we can understand that the LCM of 248,587,490,630 is 320995080.
