HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 708, 989, 186 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 708, 989, 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 708, 989, 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 708, 989, 186 is 1.

HCF(708, 989, 186) = 1

HCF of 708, 989, 186 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 708, 989, 186 is 1.

Highest Common Factor of 708,989,186 using Euclid's algorithm

Highest Common Factor of 708,989,186 is 1

Step 1: Since 989 > 708, we apply the division lemma to 989 and 708, to get

989 = 708 x 1 + 281

Step 2: Since the reminder 708 ≠ 0, we apply division lemma to 281 and 708, to get

708 = 281 x 2 + 146

Step 3: We consider the new divisor 281 and the new remainder 146, and apply the division lemma to get

281 = 146 x 1 + 135

We consider the new divisor 146 and the new remainder 135,and apply the division lemma to get

146 = 135 x 1 + 11

We consider the new divisor 135 and the new remainder 11,and apply the division lemma to get

135 = 11 x 12 + 3

We consider the new divisor 11 and the new remainder 3,and apply the division lemma to get

11 = 3 x 3 + 2

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 708 and 989 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(11,3) = HCF(135,11) = HCF(146,135) = HCF(281,146) = HCF(708,281) = HCF(989,708) .

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) .
