HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 668, 959, 828 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 668, 959, 828 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 668, 959, 828 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 668, 959, 828 is 1.

HCF(668, 959, 828) = 1

HCF of 668, 959, 828 using Euclid's algorithm

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

HCF of:

Highest common factor (HCF) of 668, 959, 828 is 1.

Highest Common Factor of 668,959,828 using Euclid's algorithm

Highest Common Factor of 668,959,828 is 1

Step 1: Since 959 > 668, we apply the division lemma to 959 and 668, to get

959 = 668 x 1 + 291

Step 2: Since the reminder 668 ≠ 0, we apply division lemma to 291 and 668, to get

668 = 291 x 2 + 86

Step 3: We consider the new divisor 291 and the new remainder 86, and apply the division lemma to get

291 = 86 x 3 + 33

We consider the new divisor 86 and the new remainder 33,and apply the division lemma to get

86 = 33 x 2 + 20

We consider the new divisor 33 and the new remainder 20,and apply the division lemma to get

33 = 20 x 1 + 13

We consider the new divisor 20 and the new remainder 13,and apply the division lemma to get

20 = 13 x 1 + 7

We consider the new divisor 13 and the new remainder 7,and apply the division lemma to get

13 = 7 x 1 + 6

We consider the new divisor 7 and the new remainder 6,and apply the division lemma to get

7 = 6 x 1 + 1

We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get

6 = 1 x 6 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 668 and 959 is 1

Notice that 1 = HCF(6,1) = HCF(7,6) = HCF(13,7) = HCF(20,13) = HCF(33,20) = HCF(86,33) = HCF(291,86) = HCF(668,291) = HCF(959,668) .

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

Step 1: Since 828 > 1, we apply the division lemma to 828 and 1, to get

828 = 1 x 828 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 828 is 1

Notice that 1 = HCF(828,1) .
