HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 846, 557 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 846, 557 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 846, 557 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 846, 557 is 1.
HCF(846, 557) = 1
HCF of 846, 557 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 846, 557 is 1.
Highest Common Factor of 846,557 is 1
Step 1: Since 846 > 557, we apply the division lemma to 846 and 557, to get
846 = 557 x 1 + 289
Step 2: Since the reminder 557 ≠ 0, we apply division lemma to 289 and 557, to get
557 = 289 x 1 + 268
Step 3: We consider the new divisor 289 and the new remainder 268, and apply the division lemma to get
289 = 268 x 1 + 21
We consider the new divisor 268 and the new remainder 21,and apply the division lemma to get
268 = 21 x 12 + 16
We consider the new divisor 21 and the new remainder 16,and apply the division lemma to get
21 = 16 x 1 + 5
We consider the new divisor 16 and the new remainder 5,and apply the division lemma to get
16 = 5 x 3 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 846 and 557 is 1
Notice that 1 = HCF(5,1) = HCF(16,5) = HCF(21,16) = HCF(268,21) = HCF(289,268) = HCF(557,289) = HCF(846,557) .
