HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 499, 688, 853 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 499, 688, 853 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 499, 688, 853 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 499, 688, 853 is 1.

HCF(499, 688, 853) = 1

HCF of 499, 688, 853 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 499, 688, 853 is 1.

Highest Common Factor of 499,688,853 using Euclid's algorithm

Highest Common Factor of 499,688,853 is 1

Step 1: Since 688 > 499, we apply the division lemma to 688 and 499, to get

688 = 499 x 1 + 189

Step 2: Since the reminder 499 ≠ 0, we apply division lemma to 189 and 499, to get

499 = 189 x 2 + 121

Step 3: We consider the new divisor 189 and the new remainder 121, and apply the division lemma to get

189 = 121 x 1 + 68

We consider the new divisor 121 and the new remainder 68,and apply the division lemma to get

121 = 68 x 1 + 53

We consider the new divisor 68 and the new remainder 53,and apply the division lemma to get

68 = 53 x 1 + 15

We consider the new divisor 53 and the new remainder 15,and apply the division lemma to get

53 = 15 x 3 + 8

We consider the new divisor 15 and the new remainder 8,and apply the division lemma to get

15 = 8 x 1 + 7

We consider the new divisor 8 and the new remainder 7,and apply the division lemma to get

8 = 7 x 1 + 1

We consider the new divisor 7 and the new remainder 1,and apply the division lemma to get

7 = 1 x 7 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 499 and 688 is 1

Notice that 1 = HCF(7,1) = HCF(8,7) = HCF(15,8) = HCF(53,15) = HCF(68,53) = HCF(121,68) = HCF(189,121) = HCF(499,189) = HCF(688,499) .

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

Step 1: Since 853 > 1, we apply the division lemma to 853 and 1, to get

853 = 1 x 853 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 853 is 1

Notice that 1 = HCF(853,1) .
