Find LCM of 620,763,924,471,315 with Prime Factorization
2 | 620, 763, 924, 471, 315 |
2 | 310, 763, 462, 471, 315 |
3 | 155, 763, 231, 471, 315 |
5 | 155, 763, 77, 157, 105 |
7 | 31, 763, 77, 157, 21 |
31, 109, 11, 157, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 31 x 109 x 11 x 157 x 3 = 7352771580
Therefore, the lowest common multiple of 620,763,924,471,315 is 7352771580.
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.
620 x 763 x 924 x 471 x 315 = 64851445335600
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.
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
763 : 1, 7, 109, 763
924 : 1, 2, 3, 4, 6, 7, 11, 12, 14, 21, 22, 28, 33, 42, 44, 66, 77, 84, 132, 154, 231, 308, 462, 924
471 : 1, 3, 157, 471
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 620,763,924,471,315, is 1.
Now, the common factors can be found like this.
620:2x 2x 5x 31
763:7x 109
924:2x 2x 3x 7x 11
471:3x 157
315:3x 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 3x 3x 5x 7x 7 = 8820
Therefore, the value for common factors is 8820.
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 = 64851445335600/(1x8820)
LCM = 64851445335600/8820
LCM = 7352771580
Thus, we can understand that the LCM of 620,763,924,471,315 is 7352771580.
