Find LCM of 624,972,521,111 with Prime Factorization
| 2 | 624, 972, 521, 111 |
| 2 | 312, 486, 521, 111 |
| 3 | 156, 243, 521, 111 |
| 52, 81, 521, 37 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 52 x 81 x 521 x 37 = 974336688
Therefore, the lowest common multiple of 624,972,521,111 is 974336688.
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.
624 x 972 x 521 x 111 = 35076120768
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.
624 : 1, 2, 3, 4, 6, 8, 12, 13, 16, 24, 26, 39, 48, 52, 78, 104, 156, 208, 312, 624
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
521 : 1, 521
111 : 1, 3, 37, 111
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 624,972,521,111, is 1.
Now, the common factors can be found like this.
624:2x 2x 2x 2x 3x 13
972:2x 2x 3x 3x 3x 3x 3
521:521
111:3x 37
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 3 = 36
Therefore, the value for common factors is 36.
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 = 35076120768/(1x36)
LCM = 35076120768/36
LCM = 974336688
Thus, we can understand that the LCM of 624,972,521,111 is 974336688.
