Find LCM of 153,617,680,494,621 with Prime Factorization
2 | 153, 617, 680, 494, 621 |
3 | 153, 617, 340, 247, 621 |
3 | 51, 617, 340, 247, 207 |
17 | 17, 617, 340, 247, 69 |
1, 617, 20, 247, 69 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 17 x 1 x 617 x 20 x 247 x 69 = 64355049720
Therefore, the lowest common multiple of 153,617,680,494,621 is 64355049720.
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.
153 x 617 x 680 x 494 x 621 = 19692645214320
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.
153 : 1, 3, 9, 17, 51, 153
617 : 1, 617
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
494 : 1, 2, 13, 19, 26, 38, 247, 494
621 : 1, 3, 9, 23, 27, 69, 207, 621
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 153,617,680,494,621, is 1.
Now, the common factors can be found like this.
153:3x 3x 17
617:617
680:2x 2x 2x 5x 17
494:2x 13x 19
621:3x 3x 3x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 17 = 306
Therefore, the value for common factors is 306.
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 = 19692645214320/(1x306)
LCM = 19692645214320/306
LCM = 64355049720
Thus, we can understand that the LCM of 153,617,680,494,621 is 64355049720.
