HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 702, 949 i.e. 13 the largest integer that leaves a remainder zero for all numbers.
HCF of 702, 949 is 13 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 702, 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 702, 949 is 13.
HCF(702, 949) = 13
HCF of 702, 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 702, 949 is 13.
Highest Common Factor of 702,949 is 13
Step 1: Since 949 > 702, we apply the division lemma to 949 and 702, to get
949 = 702 x 1 + 247
Step 2: Since the reminder 702 ≠ 0, we apply division lemma to 247 and 702, to get
702 = 247 x 2 + 208
Step 3: We consider the new divisor 247 and the new remainder 208, and apply the division lemma to get
247 = 208 x 1 + 39
We consider the new divisor 208 and the new remainder 39,and apply the division lemma to get
208 = 39 x 5 + 13
We consider the new divisor 39 and the new remainder 13,and apply the division lemma to get
39 = 13 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 13, the HCF of 702 and 949 is 13
Notice that 13 = HCF(39,13) = HCF(208,39) = HCF(247,208) = HCF(702,247) = HCF(949,702) .
