HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 571, 770 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 571, 770 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 571, 770 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 571, 770 is 1.
HCF(571, 770) = 1
HCF of 571, 770 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 571, 770 is 1.
Highest Common Factor of 571,770 is 1
Step 1: Since 770 > 571, we apply the division lemma to 770 and 571, to get
770 = 571 x 1 + 199
Step 2: Since the reminder 571 ≠ 0, we apply division lemma to 199 and 571, to get
571 = 199 x 2 + 173
Step 3: We consider the new divisor 199 and the new remainder 173, and apply the division lemma to get
199 = 173 x 1 + 26
We consider the new divisor 173 and the new remainder 26,and apply the division lemma to get
173 = 26 x 6 + 17
We consider the new divisor 26 and the new remainder 17,and apply the division lemma to get
26 = 17 x 1 + 9
We consider the new divisor 17 and the new remainder 9,and apply the division lemma to get
17 = 9 x 1 + 8
We consider the new divisor 9 and the new remainder 8,and apply the division lemma to get
9 = 8 x 1 + 1
We consider the new divisor 8 and the new remainder 1,and apply the division lemma to get
8 = 1 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 571 and 770 is 1
Notice that 1 = HCF(8,1) = HCF(9,8) = HCF(17,9) = HCF(26,17) = HCF(173,26) = HCF(199,173) = HCF(571,199) = HCF(770,571) .
