HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 557, 711 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 557, 711 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 557, 711 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 557, 711 is 1.
HCF(557, 711) = 1
HCF of 557, 711 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 557, 711 is 1.
Highest Common Factor of 557,711 is 1
Step 1: Since 711 > 557, we apply the division lemma to 711 and 557, to get
711 = 557 x 1 + 154
Step 2: Since the reminder 557 ≠ 0, we apply division lemma to 154 and 557, to get
557 = 154 x 3 + 95
Step 3: We consider the new divisor 154 and the new remainder 95, and apply the division lemma to get
154 = 95 x 1 + 59
We consider the new divisor 95 and the new remainder 59,and apply the division lemma to get
95 = 59 x 1 + 36
We consider the new divisor 59 and the new remainder 36,and apply the division lemma to get
59 = 36 x 1 + 23
We consider the new divisor 36 and the new remainder 23,and apply the division lemma to get
36 = 23 x 1 + 13
We consider the new divisor 23 and the new remainder 13,and apply the division lemma to get
23 = 13 x 1 + 10
We consider the new divisor 13 and the new remainder 10,and apply the division lemma to get
13 = 10 x 1 + 3
We consider the new divisor 10 and the new remainder 3,and apply the division lemma to get
10 = 3 x 3 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 557 and 711 is 1
Notice that 1 = HCF(3,1) = HCF(10,3) = HCF(13,10) = HCF(23,13) = HCF(36,23) = HCF(59,36) = HCF(95,59) = HCF(154,95) = HCF(557,154) = HCF(711,557) .
