The LCM of 428,744,748,152,760 is 1414236120.
Find LCM of 428,744,748,152,760 with Prime Factorization
| 2 | 428, 744, 748, 152, 760 |
| 2 | 214, 372, 374, 76, 380 |
| 2 | 107, 186, 187, 38, 190 |
| 19 | 107, 93, 187, 19, 95 |
| 107, 93, 187, 1, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 19 x 107 x 93 x 187 x 1 x 5 = 1414236120
Therefore, the lowest common multiple of 428,744,748,152,760 is 1414236120.
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.
428 x 744 x 748 x 152 x 760 = 27515377950720
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.
428 : 1, 2, 4, 107, 214, 428
744 : 1, 2, 3, 4, 6, 8, 12, 24, 31, 62, 93, 124, 186, 248, 372, 744
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
152 : 1, 2, 4, 8, 19, 38, 76, 152
760 : 1, 2, 4, 5, 8, 10, 19, 20, 38, 40, 76, 95, 152, 190, 380, 760
4 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 428,744,748,152,760, is 4.
Now, the common factors can be found like this.
428:2x 2x 107
744:2x 2x 2x 3x 31
748:2x 2x 11x 17
152:2x 2x 2x 19
760:2x 2x 2x 5x 19
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 2x 2x 2x 19 = 4864
Therefore, the value for common factors is 4864.
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 = 27515377950720/(4x4864)
LCM = 27515377950720/19456
LCM = 1414236120
Thus, we can understand that the LCM of 428,744,748,152,760 is 1414236120.
