HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 667, 146, 220 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 667, 146, 220 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 667, 146, 220 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 667, 146, 220 is 1.

HCF(667, 146, 220) = 1

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

HCF of:

Highest common factor (HCF) of 667, 146, 220 is 1.

Highest Common Factor of 667,146,220 using Euclid's algorithm

Highest Common Factor of 667,146,220 is 1

Step 1: Since 667 > 146, we apply the division lemma to 667 and 146, to get

667 = 146 x 4 + 83

Step 2: Since the reminder 146 ≠ 0, we apply division lemma to 83 and 146, to get

146 = 83 x 1 + 63

Step 3: We consider the new divisor 83 and the new remainder 63, and apply the division lemma to get

83 = 63 x 1 + 20

We consider the new divisor 63 and the new remainder 20,and apply the division lemma to get

63 = 20 x 3 + 3

We consider the new divisor 20 and the new remainder 3,and apply the division lemma to get

20 = 3 x 6 + 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 667 and 146 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(20,3) = HCF(63,20) = HCF(83,63) = HCF(146,83) = HCF(667,146) .

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

Step 1: Since 220 > 1, we apply the division lemma to 220 and 1, to get

220 = 1 x 220 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 220 is 1

Notice that 1 = HCF(220,1) .
