HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 661, 468, 186 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 661, 468, 186 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 661, 468, 186 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 661, 468, 186 is 1.

HCF(661, 468, 186) = 1

Highest common factor (HCF) of 661, 468, 186 is 1.

Highest Common Factor of 661,468,186 using Euclid's algorithm

Highest Common Factor of 661,468,186 is 1

Step 1: Since 661 > 468, we apply the division lemma to 661 and 468, to get

661 = 468 x 1 + 193

Step 2: Since the reminder 468 ≠ 0, we apply division lemma to 193 and 468, to get

468 = 193 x 2 + 82

Step 3: We consider the new divisor 193 and the new remainder 82, and apply the division lemma to get

193 = 82 x 2 + 29

We consider the new divisor 82 and the new remainder 29,and apply the division lemma to get

82 = 29 x 2 + 24

We consider the new divisor 29 and the new remainder 24,and apply the division lemma to get

29 = 24 x 1 + 5

We consider the new divisor 24 and the new remainder 5,and apply the division lemma to get

24 = 5 x 4 + 4

We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get

5 = 4 x 1 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 661 and 468 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(24,5) = HCF(29,24) = HCF(82,29) = HCF(193,82) = HCF(468,193) = HCF(661,468) .

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

Step 1: Since 186 > 1, we apply the division lemma to 186 and 1, to get

186 = 1 x 186 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 186 is 1

Notice that 1 = HCF(186,1) .
