Find LCM of 784,749,279,981,252 with Prime Factorization
2 | 784, 749, 279, 981, 252 |
2 | 392, 749, 279, 981, 126 |
3 | 196, 749, 279, 981, 63 |
3 | 196, 749, 93, 327, 21 |
7 | 196, 749, 31, 109, 7 |
28, 107, 31, 109, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 7 x 28 x 107 x 31 x 109 x 1 = 2551117968
Therefore, the lowest common multiple of 784,749,279,981,252 is 2551117968.
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.
784 x 749 x 279 x 981 x 252 = 40501548859968
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.
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
749 : 1, 7, 107, 749
279 : 1, 3, 9, 31, 93, 279
981 : 1, 3, 9, 109, 327, 981
252 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, 252
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 784,749,279,981,252, is 1.
Now, the common factors can be found like this.
784:2x 2x 2x 2x 7x 7
749:7x 107
279:3x 3x 31
981:3x 3x 109
252:2x 2x 3x 3x 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 3x 3x 7x 7 = 15876
Therefore, the value for common factors is 15876.
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 = 40501548859968/(1x15876)
LCM = 40501548859968/15876
LCM = 2551117968
Thus, we can understand that the LCM of 784,749,279,981,252 is 2551117968.
