HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 19, 75, 823, 537 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 19, 75, 823, 537 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 19, 75, 823, 537 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 19, 75, 823, 537 is 1.

HCF(19, 75, 823, 537) = 1

Highest common factor (HCF) of 19, 75, 823, 537 is 1.

Highest Common Factor of 19,75,823,537 using Euclid's algorithm

Highest Common Factor of 19,75,823,537 is 1

Step 1: Since 75 > 19, we apply the division lemma to 75 and 19, to get

75 = 19 x 3 + 18

Step 2: Since the reminder 19 ≠ 0, we apply division lemma to 18 and 19, to get

19 = 18 x 1 + 1

Step 3: We consider the new divisor 18 and the new remainder 1, and apply the division lemma to get

18 = 1 x 18 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 19 and 75 is 1

Notice that 1 = HCF(18,1) = HCF(19,18) = HCF(75,19) .


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

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

823 = 1 x 823 + 0

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

Notice that 1 = HCF(823,1) .


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

Step 1: Since 537 > 1, we apply the division lemma to 537 and 1, to get

537 = 1 x 537 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 537 is 1

Notice that 1 = HCF(537,1) .
