The LCM of 773,200,978,639,640 is 257642755200.
Find LCM of 773,200,978,639,640 with Prime Factorization
| 2 | 773, 200, 978, 639, 640 |
| 2 | 773, 100, 489, 639, 320 |
| 2 | 773, 50, 489, 639, 160 |
| 3 | 773, 25, 489, 639, 80 |
| 5 | 773, 25, 163, 213, 80 |
| 773, 5, 163, 213, 16 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 773 x 5 x 163 x 213 x 16 = 257642755200
Therefore, the lowest common multiple of 773,200,978,639,640 is 257642755200.
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.
773 x 200 x 978 x 639 x 640 = 61834261248000
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.
773 : 1, 773
200 : 1, 2, 4, 5, 8, 10, 20, 25, 40, 50, 100, 200
978 : 1, 2, 3, 6, 163, 326, 489, 978
639 : 1, 3, 9, 71, 213, 639
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 773,200,978,639,640, is 1.
Now, the common factors can be found like this.
773:773
200:2x 2x 2x 5x 5
978:2x 3x 163
639:3x 3x 71
640:2x 2x 2x 2x 2x 2x 2x 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 3x 5 = 240
Therefore, the value for common factors is 240.
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 = 61834261248000/(1x240)
LCM = 61834261248000/240
LCM = 257642755200
Thus, we can understand that the LCM of 773,200,978,639,640 is 257642755200.
