Find LCM of 978,620,624,299,124 with Prime Factorization
2 | 978, 620, 624, 299, 124 |
2 | 489, 310, 312, 299, 62 |
3 | 489, 155, 156, 299, 31 |
13 | 163, 155, 52, 299, 31 |
31 | 163, 155, 4, 23, 31 |
163, 5, 4, 23, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 13 x 31 x 163 x 5 x 4 x 23 x 1 = 362603280
Therefore, the lowest common multiple of 978,620,624,299,124 is 362603280.
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.
978 x 620 x 624 x 299 x 124 = 14028395696640
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.
978 : 1, 2, 3, 6, 163, 326, 489, 978
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
624 : 1, 2, 3, 4, 6, 8, 12, 13, 16, 24, 26, 39, 48, 52, 78, 104, 156, 208, 312, 624
299 : 1, 13, 23, 299
124 : 1, 2, 4, 31, 62, 124
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 978,620,624,299,124, is 1.
Now, the common factors can be found like this.
978:2x 3x 163
620:2x 2x 5x 31
624:2x 2x 2x 2x 3x 13
299:13x 23
124:2x 2x 31
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 2x 3x 13x 31 = 38688
Therefore, the value for common factors is 38688.
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 = 14028395696640/(1x38688)
LCM = 14028395696640/38688
LCM = 362603280
Thus, we can understand that the LCM of 978,620,624,299,124 is 362603280.
