HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 493, 852 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 493, 852 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 493, 852 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 493, 852 is 1.
HCF(493, 852) = 1
HCF of 493, 852 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 493, 852 is 1.
Highest Common Factor of 493,852 is 1
Step 1: Since 852 > 493, we apply the division lemma to 852 and 493, to get
852 = 493 x 1 + 359
Step 2: Since the reminder 493 ≠ 0, we apply division lemma to 359 and 493, to get
493 = 359 x 1 + 134
Step 3: We consider the new divisor 359 and the new remainder 134, and apply the division lemma to get
359 = 134 x 2 + 91
We consider the new divisor 134 and the new remainder 91,and apply the division lemma to get
134 = 91 x 1 + 43
We consider the new divisor 91 and the new remainder 43,and apply the division lemma to get
91 = 43 x 2 + 5
We consider the new divisor 43 and the new remainder 5,and apply the division lemma to get
43 = 5 x 8 + 3
We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get
5 = 3 x 1 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 493 and 852 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(43,5) = HCF(91,43) = HCF(134,91) = HCF(359,134) = HCF(493,359) = HCF(852,493) .
