Given numbers are 767,421,421,440
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 767,421,421,440 is 142079080.
Find LCM of 767,421,421,440 with Prime Factorization
421 | 767, 421, 421, 440 |
767, 1, 1, 440 |
Multiply the prime numbers at the bottom and the left side.
421 x 767 x 1 x 1 x 440 = 142079080
Therefore, the lowest common multiple of 767,421,421,440 is 142079080.
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.
767 x 421 x 421 x 440 = 59815292680
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.
767 : 1, 13, 59, 767
421 : 1, 421
421 : 1, 421
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 767,421,421,440, is 1.
Now, the common factors can be found like this.
767:13x 59
421:421
421:421
440:2x 2x 2x 5x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
421 = 421
Therefore, the value for common factors is 421.
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 = 59815292680/(1x421)
LCM = 59815292680/421
LCM = 142079080
Thus, we can understand that the LCM of 767,421,421,440 is 142079080.
