HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 949, 691, 144 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 949, 691, 144 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, 691, 144 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, 691, 144 is 1.
HCF(949, 691, 144) = 1
HCF of 949, 691, 144 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 949, 691, 144 is 1.
Highest Common Factor of 949,691,144 is 1
Step 1: Since 949 > 691, we apply the division lemma to 949 and 691, to get
949 = 691 x 1 + 258
Step 2: Since the reminder 691 ≠ 0, we apply division lemma to 258 and 691, to get
691 = 258 x 2 + 175
Step 3: We consider the new divisor 258 and the new remainder 175, and apply the division lemma to get
258 = 175 x 1 + 83
We consider the new divisor 175 and the new remainder 83,and apply the division lemma to get
175 = 83 x 2 + 9
We consider the new divisor 83 and the new remainder 9,and apply the division lemma to get
83 = 9 x 9 + 2
We consider the new divisor 9 and the new remainder 2,and apply the division lemma to get
9 = 2 x 4 + 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 949 and 691 is 1
Notice that 1 = HCF(2,1) = HCF(9,2) = HCF(83,9) = HCF(175,83) = HCF(258,175) = HCF(691,258) = HCF(949,691) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 144 > 1, we apply the division lemma to 144 and 1, to get
144 = 1 x 144 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 144 is 1
Notice that 1 = HCF(144,1) .
