HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 648, 97 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 648, 97 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 648, 97 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 648, 97 is 1.
HCF(648, 97) = 1
HCF of 648, 97 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 648, 97 is 1.
Highest Common Factor of 648,97 is 1
Step 1: Since 648 > 97, we apply the division lemma to 648 and 97, to get
648 = 97 x 6 + 66
Step 2: Since the reminder 97 ≠ 0, we apply division lemma to 66 and 97, to get
97 = 66 x 1 + 31
Step 3: We consider the new divisor 66 and the new remainder 31, and apply the division lemma to get
66 = 31 x 2 + 4
We consider the new divisor 31 and the new remainder 4,and apply the division lemma to get
31 = 4 x 7 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 648 and 97 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(31,4) = HCF(66,31) = HCF(97,66) = HCF(648,97) .
