Find LCM of 248,562,870,676,690 with Prime Factorization
2 | 248, 562, 870, 676, 690 |
2 | 124, 281, 435, 338, 345 |
3 | 62, 281, 435, 169, 345 |
5 | 62, 281, 145, 169, 115 |
62, 281, 29, 169, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 62 x 281 x 29 x 169 x 23 = 117831606360
Therefore, the lowest common multiple of 248,562,870,676,690 is 117831606360.
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 562 x 870 x 676 x 690 = 56559171052800
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
562 : 1, 2, 281, 562
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 248,562,870,676,690, is 2.
Now, the common factors can be found like this.
248:2x 2x 2x 31
562:2x 281
870:2x 3x 5x 29
676:2x 2x 13x 13
690:2x 3x 5x 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 2x 2x 2x 3x 5 = 240
Therefore, the value for common factors is 240.
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 = 56559171052800/(2x240)
LCM = 56559171052800/480
LCM = 117831606360
Thus, we can understand that the LCM of 248,562,870,676,690 is 117831606360.
