HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 486, 1781 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 486, 1781 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 486, 1781 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 486, 1781 is 1.
HCF(486, 1781) = 1
HCF of 486, 1781 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 486, 1781 is 1.
Highest Common Factor of 486,1781 is 1
Step 1: Since 1781 > 486, we apply the division lemma to 1781 and 486, to get
1781 = 486 x 3 + 323
Step 2: Since the reminder 486 ≠ 0, we apply division lemma to 323 and 486, to get
486 = 323 x 1 + 163
Step 3: We consider the new divisor 323 and the new remainder 163, and apply the division lemma to get
323 = 163 x 1 + 160
We consider the new divisor 163 and the new remainder 160,and apply the division lemma to get
163 = 160 x 1 + 3
We consider the new divisor 160 and the new remainder 3,and apply the division lemma to get
160 = 3 x 53 + 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 486 and 1781 is 1
Notice that 1 = HCF(3,1) = HCF(160,3) = HCF(163,160) = HCF(323,163) = HCF(486,323) = HCF(1781,486) .
