HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 585, 431 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 585, 431 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 585, 431 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 585, 431 is 1.
HCF(585, 431) = 1
HCF of 585, 431 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 585, 431 is 1.
Highest Common Factor of 585,431 is 1
Step 1: Since 585 > 431, we apply the division lemma to 585 and 431, to get
585 = 431 x 1 + 154
Step 2: Since the reminder 431 ≠ 0, we apply division lemma to 154 and 431, to get
431 = 154 x 2 + 123
Step 3: We consider the new divisor 154 and the new remainder 123, and apply the division lemma to get
154 = 123 x 1 + 31
We consider the new divisor 123 and the new remainder 31,and apply the division lemma to get
123 = 31 x 3 + 30
We consider the new divisor 31 and the new remainder 30,and apply the division lemma to get
31 = 30 x 1 + 1
We consider the new divisor 30 and the new remainder 1,and apply the division lemma to get
30 = 1 x 30 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 585 and 431 is 1
Notice that 1 = HCF(30,1) = HCF(31,30) = HCF(123,31) = HCF(154,123) = HCF(431,154) = HCF(585,431) .
