HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 949, 120, 511 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 949, 120, 511 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 949, 120, 511 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 949, 120, 511 is 1.

HCF(949, 120, 511) = 1

HCF of 949, 120, 511 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 949, 120, 511 is 1.

Highest Common Factor of 949,120,511 using Euclid's algorithm

Highest Common Factor of 949,120,511 is 1

Step 1: Since 949 > 120, we apply the division lemma to 949 and 120, to get

949 = 120 x 7 + 109

Step 2: Since the reminder 120 ≠ 0, we apply division lemma to 109 and 120, to get

120 = 109 x 1 + 11

Step 3: We consider the new divisor 109 and the new remainder 11, and apply the division lemma to get

109 = 11 x 9 + 10

We consider the new divisor 11 and the new remainder 10,and apply the division lemma to get

11 = 10 x 1 + 1

We consider the new divisor 10 and the new remainder 1,and apply the division lemma to get

10 = 1 x 10 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 949 and 120 is 1

Notice that 1 = HCF(10,1) = HCF(11,10) = HCF(109,11) = HCF(120,109) = HCF(949,120) .


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

Step 1: Since 511 > 1, we apply the division lemma to 511 and 1, to get

511 = 1 x 511 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 511 is 1

Notice that 1 = HCF(511,1) .
