HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 970, 949 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 970, 949 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 970, 949 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 970, 949 is 1.
HCF(970, 949) = 1
HCF of 970, 949 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 970, 949 is 1.
Highest Common Factor of 970,949 is 1
Step 1: Since 970 > 949, we apply the division lemma to 970 and 949, to get
970 = 949 x 1 + 21
Step 2: Since the reminder 949 ≠ 0, we apply division lemma to 21 and 949, to get
949 = 21 x 45 + 4
Step 3: We consider the new divisor 21 and the new remainder 4, and apply the division lemma to get
21 = 4 x 5 + 1
We consider the new divisor 4 and the new remainder 1, and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 970 and 949 is 1
Notice that 1 = HCF(4,1) = HCF(21,4) = HCF(949,21) = HCF(970,949) .
