HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 55, 473 i.e. 11 the largest integer that leaves a remainder zero for all numbers.
HCF of 55, 473 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 55, 473 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 55, 473 is 11.
HCF(55, 473) = 11
HCF of 55, 473 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 55, 473 is 11.
Highest Common Factor of 55,473 is 11
Step 1: Since 473 > 55, we apply the division lemma to 473 and 55, to get
473 = 55 x 8 + 33
Step 2: Since the reminder 55 ≠ 0, we apply division lemma to 33 and 55, to get
55 = 33 x 1 + 22
Step 3: We consider the new divisor 33 and the new remainder 22, and apply the division lemma to get
33 = 22 x 1 + 11
We consider the new divisor 22 and the new remainder 11, and apply the division lemma to get
22 = 11 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 11, the HCF of 55 and 473 is 11
Notice that 11 = HCF(22,11) = HCF(33,22) = HCF(55,33) = HCF(473,55) .
