HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 461, 794, 688 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 461, 794, 688 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 461, 794, 688 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 461, 794, 688 is 1.

HCF(461, 794, 688) = 1

HCF of 461, 794, 688 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 461, 794, 688 is 1.

Highest Common Factor of 461,794,688 using Euclid's algorithm

Highest Common Factor of 461,794,688 is 1

Step 1: Since 794 > 461, we apply the division lemma to 794 and 461, to get

794 = 461 x 1 + 333

Step 2: Since the reminder 461 ≠ 0, we apply division lemma to 333 and 461, to get

461 = 333 x 1 + 128

Step 3: We consider the new divisor 333 and the new remainder 128, and apply the division lemma to get

333 = 128 x 2 + 77

We consider the new divisor 128 and the new remainder 77,and apply the division lemma to get

128 = 77 x 1 + 51

We consider the new divisor 77 and the new remainder 51,and apply the division lemma to get

77 = 51 x 1 + 26

We consider the new divisor 51 and the new remainder 26,and apply the division lemma to get

51 = 26 x 1 + 25

We consider the new divisor 26 and the new remainder 25,and apply the division lemma to get

26 = 25 x 1 + 1

We consider the new divisor 25 and the new remainder 1,and apply the division lemma to get

25 = 1 x 25 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 461 and 794 is 1

Notice that 1 = HCF(25,1) = HCF(26,25) = HCF(51,26) = HCF(77,51) = HCF(128,77) = HCF(333,128) = HCF(461,333) = HCF(794,461) .

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

Step 1: Since 688 > 1, we apply the division lemma to 688 and 1, to get

688 = 1 x 688 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 688 is 1

Notice that 1 = HCF(688,1) .
