HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 169, 604, 989 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 169, 604, 989 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 169, 604, 989 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 169, 604, 989 is 1.

HCF(169, 604, 989) = 1

HCF of 169, 604, 989 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 169, 604, 989 is 1.

Highest Common Factor of 169,604,989 using Euclid's algorithm

Highest Common Factor of 169,604,989 is 1

Step 1: Since 604 > 169, we apply the division lemma to 604 and 169, to get

604 = 169 x 3 + 97

Step 2: Since the reminder 169 ≠ 0, we apply division lemma to 97 and 169, to get

169 = 97 x 1 + 72

Step 3: We consider the new divisor 97 and the new remainder 72, and apply the division lemma to get

97 = 72 x 1 + 25

We consider the new divisor 72 and the new remainder 25,and apply the division lemma to get

72 = 25 x 2 + 22

We consider the new divisor 25 and the new remainder 22,and apply the division lemma to get

25 = 22 x 1 + 3

We consider the new divisor 22 and the new remainder 3,and apply the division lemma to get

22 = 3 x 7 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 169 and 604 is 1

Notice that 1 = HCF(3,1) = HCF(22,3) = HCF(25,22) = HCF(72,25) = HCF(97,72) = HCF(169,97) = HCF(604,169) .

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

Step 1: Since 989 > 1, we apply the division lemma to 989 and 1, to get

989 = 1 x 989 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 989 is 1

Notice that 1 = HCF(989,1) .
