HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 660, 967, 486 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 660, 967, 486 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 660, 967, 486 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 660, 967, 486 is 1.

HCF(660, 967, 486) = 1

HCF of 660, 967, 486 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 660, 967, 486 is 1.

Highest Common Factor of 660,967,486 using Euclid's algorithm

Highest Common Factor of 660,967,486 is 1

Step 1: Since 967 > 660, we apply the division lemma to 967 and 660, to get

967 = 660 x 1 + 307

Step 2: Since the reminder 660 ≠ 0, we apply division lemma to 307 and 660, to get

660 = 307 x 2 + 46

Step 3: We consider the new divisor 307 and the new remainder 46, and apply the division lemma to get

307 = 46 x 6 + 31

We consider the new divisor 46 and the new remainder 31,and apply the division lemma to get

46 = 31 x 1 + 15

We consider the new divisor 31 and the new remainder 15,and apply the division lemma to get

31 = 15 x 2 + 1

We consider the new divisor 15 and the new remainder 1,and apply the division lemma to get

15 = 1 x 15 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 660 and 967 is 1

Notice that 1 = HCF(15,1) = HCF(31,15) = HCF(46,31) = HCF(307,46) = HCF(660,307) = HCF(967,660) .

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

Step 1: Since 486 > 1, we apply the division lemma to 486 and 1, to get

486 = 1 x 486 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 486 is 1

Notice that 1 = HCF(486,1) .
