Given numbers are 978,182,425,541,784
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 978,182,425,541,784 is 1145920448400.
Find LCM of 978,182,425,541,784 with Prime Factorization
| 2 | 978, 182, 425, 541, 784 |
| 7 | 489, 91, 425, 541, 392 |
| 489, 13, 425, 541, 56 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 489 x 13 x 425 x 541 x 56 = 1145920448400
Therefore, the lowest common multiple of 978,182,425,541,784 is 1145920448400.
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.
978 x 182 x 425 x 541 x 784 = 32085772555200
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.
978 : 1, 2, 3, 6, 163, 326, 489, 978
182 : 1, 2, 7, 13, 14, 26, 91, 182
425 : 1, 5, 17, 25, 85, 425
541 : 1, 541
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 978,182,425,541,784, is 1.
Now, the common factors can be found like this.
978:2x 3x 163
182:2x 7x 13
425:5x 5x 17
541:541
784:2x 2x 2x 2x 7x 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 7 = 28
Therefore, the value for common factors is 28.
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 = 32085772555200/(1x28)
LCM = 32085772555200/28
LCM = 1145920448400
Thus, we can understand that the LCM of 978,182,425,541,784 is 1145920448400.
