HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 989, 670, 33 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 989, 670, 33 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 989, 670, 33 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 989, 670, 33 is 1.

HCF(989, 670, 33) = 1

HCF of 989, 670, 33 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 989, 670, 33 is 1.

Highest Common Factor of 989,670,33 using Euclid's algorithm

Highest Common Factor of 989,670,33 is 1

Step 1: Since 989 > 670, we apply the division lemma to 989 and 670, to get

989 = 670 x 1 + 319

Step 2: Since the reminder 670 ≠ 0, we apply division lemma to 319 and 670, to get

670 = 319 x 2 + 32

Step 3: We consider the new divisor 319 and the new remainder 32, and apply the division lemma to get

319 = 32 x 9 + 31

We consider the new divisor 32 and the new remainder 31,and apply the division lemma to get

32 = 31 x 1 + 1

We consider the new divisor 31 and the new remainder 1,and apply the division lemma to get

31 = 1 x 31 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 989 and 670 is 1

Notice that 1 = HCF(31,1) = HCF(32,31) = HCF(319,32) = HCF(670,319) = HCF(989,670) .


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

Step 1: Since 33 > 1, we apply the division lemma to 33 and 1, to get

33 = 1 x 33 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 33 is 1

Notice that 1 = HCF(33,1) .
