HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 823, 625, 380 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 823, 625, 380 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 823, 625, 380 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 823, 625, 380 is 1.

HCF(823, 625, 380) = 1

Highest common factor (HCF) of 823, 625, 380 is 1.

Highest Common Factor of 823,625,380 using Euclid's algorithm

Highest Common Factor of 823,625,380 is 1

Step 1: Since 823 > 625, we apply the division lemma to 823 and 625, to get

823 = 625 x 1 + 198

Step 2: Since the reminder 625 ≠ 0, we apply division lemma to 198 and 625, to get

625 = 198 x 3 + 31

Step 3: We consider the new divisor 198 and the new remainder 31, and apply the division lemma to get

198 = 31 x 6 + 12

We consider the new divisor 31 and the new remainder 12,and apply the division lemma to get

31 = 12 x 2 + 7

We consider the new divisor 12 and the new remainder 7,and apply the division lemma to get

12 = 7 x 1 + 5

We consider the new divisor 7 and the new remainder 5,and apply the division lemma to get

7 = 5 x 1 + 2

We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get

5 = 2 x 2 + 1

We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get

2 = 1 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 823 and 625 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(7,5) = HCF(12,7) = HCF(31,12) = HCF(198,31) = HCF(625,198) = HCF(823,625) .

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

Step 1: Since 380 > 1, we apply the division lemma to 380 and 1, to get

380 = 1 x 380 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 380 is 1

Notice that 1 = HCF(380,1) .
