Calculate the LCM of 973,409,578,890

Given numbers are 973,409,578,890

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

The LCM of 973,409,578,890 is 102358519970.

Find LCM of 973,409,578,890 with Prime Factorization


2 973, 409, 578, 890
973, 409, 289, 445

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

2 x 973 x 409 x 289 x 445 = 102358519970

Therefore, the lowest common multiple of 973,409,578,890 is 102358519970.

LCM Formula to Find Lowest Common Multiple of 973,409,578,890

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.

973 x 409 x 578 x 890 = 204717039940

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.

973 : 1, 7, 139, 973

409 : 1, 409

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

890 : 1, 2, 5, 10, 89, 178, 445, 890

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 973,409,578,890, is 1.

Now, the common factors can be found like this.

973:7x 139

409:409

578:2x 17x 17

890:2x 5x 89

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2 = 2

Therefore, the value for common factors is 2.

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 = 204717039940/(1x2)

LCM = 204717039940/2

LCM = 102358519970

Thus, we can understand that the LCM of 973,409,578,890 is 102358519970.
