HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 653, 278 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 653, 278 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 653, 278 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 653, 278 is 1.
HCF(653, 278) = 1
HCF of 653, 278 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 653, 278 is 1.
Highest Common Factor of 653,278 is 1
Step 1: Since 653 > 278, we apply the division lemma to 653 and 278, to get
653 = 278 x 2 + 97
Step 2: Since the reminder 278 ≠ 0, we apply division lemma to 97 and 278, to get
278 = 97 x 2 + 84
Step 3: We consider the new divisor 97 and the new remainder 84, and apply the division lemma to get
97 = 84 x 1 + 13
We consider the new divisor 84 and the new remainder 13,and apply the division lemma to get
84 = 13 x 6 + 6
We consider the new divisor 13 and the new remainder 6,and apply the division lemma to get
13 = 6 x 2 + 1
We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 653 and 278 is 1
Notice that 1 = HCF(6,1) = HCF(13,6) = HCF(84,13) = HCF(97,84) = HCF(278,97) = HCF(653,278) .
