Calculate the LCM of 392,534,578,774

Given numbers are 392,534,578,774

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 392,534,578,774 is 3901978584.

Find LCM of 392,534,578,774 with Prime Factorization


2 392, 534, 578, 774
3 196, 267, 289, 387
196, 89, 289, 129

Multiply the prime numbers at the bottom and the left side.

2 x 3 x 196 x 89 x 289 x 129 = 3901978584

Therefore, the lowest common multiple of 392,534,578,774 is 3901978584.

LCM Formula to Find Lowest Common Multiple of 392,534,578,774

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.

392 x 534 x 578 x 774 = 93647486016

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.

392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392

534 : 1, 2, 3, 6, 89, 178, 267, 534

578 : 1, 2, 17, 34, 289, 578

774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 392,534,578,774, is 2.

Now, the common factors can be found like this.

392:2x 2x 2x 7x 7

534:2x 3x 89

578:2x 17x 17

774:2x 3x 3x 43

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 3 = 12

Therefore, the value for common factors is 12.

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 = 93647486016/(2x12)

LCM = 93647486016/24

LCM = 3901978584

Thus, we can understand that the LCM of 392,534,578,774 is 3901978584.
