HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 878, 235, 690 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 878, 235, 690 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 878, 235, 690 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 878, 235, 690 is 1.

HCF(878, 235, 690) = 1

Highest common factor (HCF) of 878, 235, 690 is 1.

Highest Common Factor of 878,235,690 using Euclid's algorithm

Highest Common Factor of 878,235,690 is 1

Step 1: Since 878 > 235, we apply the division lemma to 878 and 235, to get

878 = 235 x 3 + 173

Step 2: Since the reminder 235 ≠ 0, we apply division lemma to 173 and 235, to get

235 = 173 x 1 + 62

Step 3: We consider the new divisor 173 and the new remainder 62, and apply the division lemma to get

173 = 62 x 2 + 49

We consider the new divisor 62 and the new remainder 49,and apply the division lemma to get

62 = 49 x 1 + 13

We consider the new divisor 49 and the new remainder 13,and apply the division lemma to get

49 = 13 x 3 + 10

We consider the new divisor 13 and the new remainder 10,and apply the division lemma to get

13 = 10 x 1 + 3

We consider the new divisor 10 and the new remainder 3,and apply the division lemma to get

10 = 3 x 3 + 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 878 and 235 is 1

Notice that 1 = HCF(3,1) = HCF(10,3) = HCF(13,10) = HCF(49,13) = HCF(62,49) = HCF(173,62) = HCF(235,173) = HCF(878,235) .

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

Step 1: Since 690 > 1, we apply the division lemma to 690 and 1, to get

690 = 1 x 690 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 690 is 1

Notice that 1 = HCF(690,1) .
