HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 835, 642, 524 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 835, 642, 524 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 835, 642, 524 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 835, 642, 524 is 1.

HCF(835, 642, 524) = 1

Highest common factor (HCF) of 835, 642, 524 is 1.

Highest Common Factor of 835,642,524 using Euclid's algorithm

Highest Common Factor of 835,642,524 is 1

Step 1: Since 835 > 642, we apply the division lemma to 835 and 642, to get

835 = 642 x 1 + 193

Step 2: Since the reminder 642 ≠ 0, we apply division lemma to 193 and 642, to get

642 = 193 x 3 + 63

Step 3: We consider the new divisor 193 and the new remainder 63, and apply the division lemma to get

193 = 63 x 3 + 4

We consider the new divisor 63 and the new remainder 4,and apply the division lemma to get

63 = 4 x 15 + 3

We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get

4 = 3 x 1 + 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 835 and 642 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(63,4) = HCF(193,63) = HCF(642,193) = HCF(835,642) .

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

Step 1: Since 524 > 1, we apply the division lemma to 524 and 1, to get

524 = 1 x 524 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 524 is 1

Notice that 1 = HCF(524,1) .
