HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 969, 625, 484 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 969, 625, 484 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 969, 625, 484 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 969, 625, 484 is 1.

HCF(969, 625, 484) = 1

Highest common factor (HCF) of 969, 625, 484 is 1.

Highest Common Factor of 969,625,484 using Euclid's algorithm

Highest Common Factor of 969,625,484 is 1

Step 1: Since 969 > 625, we apply the division lemma to 969 and 625, to get

969 = 625 x 1 + 344

Step 2: Since the reminder 625 ≠ 0, we apply division lemma to 344 and 625, to get

625 = 344 x 1 + 281

Step 3: We consider the new divisor 344 and the new remainder 281, and apply the division lemma to get

344 = 281 x 1 + 63

We consider the new divisor 281 and the new remainder 63,and apply the division lemma to get

281 = 63 x 4 + 29

We consider the new divisor 63 and the new remainder 29,and apply the division lemma to get

63 = 29 x 2 + 5

We consider the new divisor 29 and the new remainder 5,and apply the division lemma to get

29 = 5 x 5 + 4

We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get

5 = 4 x 1 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 969 and 625 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(29,5) = HCF(63,29) = HCF(281,63) = HCF(344,281) = HCF(625,344) = HCF(969,625) .

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

Step 1: Since 484 > 1, we apply the division lemma to 484 and 1, to get

484 = 1 x 484 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 484 is 1

Notice that 1 = HCF(484,1) .
