HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 969, 642, 24, 878 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 969, 642, 24, 878 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, 642, 24, 878 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, 642, 24, 878 is 1.

HCF(969, 642, 24, 878) = 1

Highest common factor (HCF) of 969, 642, 24, 878 is 1.

Highest Common Factor of 969,642,24,878 using Euclid's algorithm

Highest Common Factor of 969,642,24,878 is 1

Step 1: Since 969 > 642, we apply the division lemma to 969 and 642, to get

969 = 642 x 1 + 327

Step 2: Since the reminder 642 ≠ 0, we apply division lemma to 327 and 642, to get

642 = 327 x 1 + 315

Step 3: We consider the new divisor 327 and the new remainder 315, and apply the division lemma to get

327 = 315 x 1 + 12

We consider the new divisor 315 and the new remainder 12,and apply the division lemma to get

315 = 12 x 26 + 3

We consider the new divisor 12 and the new remainder 3,and apply the division lemma to get

12 = 3 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 969 and 642 is 3

Notice that 3 = HCF(12,3) = HCF(315,12) = HCF(327,315) = HCF(642,327) = HCF(969,642) .

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

Step 1: Since 24 > 3, we apply the division lemma to 24 and 3, to get

24 = 3 x 8 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 24 is 3

Notice that 3 = HCF(24,3) .

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

Step 1: Since 878 > 3, we apply the division lemma to 878 and 3, to get

878 = 3 x 292 + 2

Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 2 and 3, to get

3 = 2 x 1 + 1

Step 3: 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 3 and 878 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(878,3) .
