HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 850, 385, 238 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 850, 385, 238 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 850, 385, 238 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 850, 385, 238 is 1.

HCF(850, 385, 238) = 1

Highest common factor (HCF) of 850, 385, 238 is 1.

Highest Common Factor of 850,385,238 using Euclid's algorithm

Highest Common Factor of 850,385,238 is 1

Step 1: Since 850 > 385, we apply the division lemma to 850 and 385, to get

850 = 385 x 2 + 80

Step 2: Since the reminder 385 ≠ 0, we apply division lemma to 80 and 385, to get

385 = 80 x 4 + 65

Step 3: We consider the new divisor 80 and the new remainder 65, and apply the division lemma to get

80 = 65 x 1 + 15

We consider the new divisor 65 and the new remainder 15,and apply the division lemma to get

65 = 15 x 4 + 5

We consider the new divisor 15 and the new remainder 5,and apply the division lemma to get

15 = 5 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 850 and 385 is 5

Notice that 5 = HCF(15,5) = HCF(65,15) = HCF(80,65) = HCF(385,80) = HCF(850,385) .


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

Step 1: Since 238 > 5, we apply the division lemma to 238 and 5, to get

238 = 5 x 47 + 3

Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 3 and 5, to get

5 = 3 x 1 + 2

Step 3: We consider the new divisor 3 and the new remainder 2, and apply the division lemma to get

3 = 2 x 1 + 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 5 and 238 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(238,5) .
