HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 365, 235, 658 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 365, 235, 658 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 365, 235, 658 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 365, 235, 658 is 1.

HCF(365, 235, 658) = 1

Highest common factor (HCF) of 365, 235, 658 is 1.

Highest Common Factor of 365,235,658 using Euclid's algorithm

Highest Common Factor of 365,235,658 is 1

Step 1: Since 365 > 235, we apply the division lemma to 365 and 235, to get

365 = 235 x 1 + 130

Step 2: Since the reminder 235 ≠ 0, we apply division lemma to 130 and 235, to get

235 = 130 x 1 + 105

Step 3: We consider the new divisor 130 and the new remainder 105, and apply the division lemma to get

130 = 105 x 1 + 25

We consider the new divisor 105 and the new remainder 25,and apply the division lemma to get

105 = 25 x 4 + 5

We consider the new divisor 25 and the new remainder 5,and apply the division lemma to get

25 = 5 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 365 and 235 is 5

Notice that 5 = HCF(25,5) = HCF(105,25) = HCF(130,105) = HCF(235,130) = HCF(365,235) .

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

Step 1: Since 658 > 5, we apply the division lemma to 658 and 5, to get

658 = 5 x 131 + 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 658 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(658,5) .
