HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 825, 253 i.e. 11 the largest integer that leaves a remainder zero for all numbers.
HCF of 825, 253 is 11 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 825, 253 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 825, 253 is 11.
HCF(825, 253) = 11
HCF of 825, 253 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 825, 253 is 11.
Highest Common Factor of 825,253 is 11
Step 1: Since 825 > 253, we apply the division lemma to 825 and 253, to get
825 = 253 x 3 + 66
Step 2: Since the reminder 253 ≠ 0, we apply division lemma to 66 and 253, to get
253 = 66 x 3 + 55
Step 3: We consider the new divisor 66 and the new remainder 55, and apply the division lemma to get
66 = 55 x 1 + 11
We consider the new divisor 55 and the new remainder 11, and apply the division lemma to get
55 = 11 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 11, the HCF of 825 and 253 is 11
Notice that 11 = HCF(55,11) = HCF(66,55) = HCF(253,66) = HCF(825,253) .
