HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 899, 511, 642 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 899, 511, 642 is 1 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.

Consider we have numbers 899, 511, 642 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b

Highest common factor (HCF) of 899, 511, 642 is 1.

HCF(899, 511, 642) = 1

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 899, 511, 642 is 1.

Highest Common Factor of 899,511,642 using Euclid's algorithm

Highest Common Factor of 899,511,642 is 1

Step 1: Since 899 > 511, we apply the division lemma to 899 and 511, to get

899 = 511 x 1 + 388

Step 2: Since the reminder 511 ≠ 0, we apply division lemma to 388 and 511, to get

511 = 388 x 1 + 123

Step 3: We consider the new divisor 388 and the new remainder 123, and apply the division lemma to get

388 = 123 x 3 + 19

We consider the new divisor 123 and the new remainder 19,and apply the division lemma to get

123 = 19 x 6 + 9

We consider the new divisor 19 and the new remainder 9,and apply the division lemma to get

19 = 9 x 2 + 1

We consider the new divisor 9 and the new remainder 1,and apply the division lemma to get

9 = 1 x 9 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 899 and 511 is 1

Notice that 1 = HCF(9,1) = HCF(19,9) = HCF(123,19) = HCF(388,123) = HCF(511,388) = HCF(899,511) .

We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma

Step 1: Since 642 > 1, we apply the division lemma to 642 and 1, to get

642 = 1 x 642 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 642 is 1

Notice that 1 = HCF(642,1) .
