Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 5 x 19 x 1 x 29 x 89 x 227 x 3 = 8014934160
Therefore, the lowest common multiple of 912,551,890,454,720 is 8014934160.
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.
912 x 551 x 890 x 454 x 720 = 146192399078400
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.
912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912
551 : 1, 19, 29, 551
890 : 1, 2, 5, 10, 89, 178, 445, 890
454 : 1, 2, 227, 454
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 912,551,890,454,720, is 1.
Now, the common factors can be found like this.
912:2x 2x 2x 2x 3x 19
551:19x 29
890:2x 5x 89
454:2x 227
720:2x 2x 2x 2x 3x 3x 5
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 3x 5x 19 = 18240
Therefore, the value for common factors is 18240.
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 = 146192399078400/(1x18240)
LCM = 146192399078400/18240
LCM = 8014934160
Thus, we can understand that the LCM of 912,551,890,454,720 is 8014934160.
