HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 476, 561 i.e. 17 the largest integer that leaves a remainder zero for all numbers.
HCF of 476, 561 is 17 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 476, 561 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 476, 561 is 17.
HCF(476, 561) = 17
HCF of 476, 561 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 476, 561 is 17.
Highest Common Factor of 476,561 is 17
Step 1: Since 561 > 476, we apply the division lemma to 561 and 476, to get
561 = 476 x 1 + 85
Step 2: Since the reminder 476 ≠ 0, we apply division lemma to 85 and 476, to get
476 = 85 x 5 + 51
Step 3: We consider the new divisor 85 and the new remainder 51, and apply the division lemma to get
85 = 51 x 1 + 34
We consider the new divisor 51 and the new remainder 34,and apply the division lemma to get
51 = 34 x 1 + 17
We consider the new divisor 34 and the new remainder 17,and apply the division lemma to get
34 = 17 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 17, the HCF of 476 and 561 is 17
Notice that 17 = HCF(34,17) = HCF(51,34) = HCF(85,51) = HCF(476,85) = HCF(561,476) .
