HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 1091, 1820 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 1091, 1820 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 1091, 1820 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 1091, 1820 is 1.
HCF(1091, 1820) = 1
HCF of 1091, 1820 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 1091, 1820 is 1.
Highest Common Factor of 1091,1820 is 1
Step 1: Since 1820 > 1091, we apply the division lemma to 1820 and 1091, to get
1820 = 1091 x 1 + 729
Step 2: Since the reminder 1091 ≠ 0, we apply division lemma to 729 and 1091, to get
1091 = 729 x 1 + 362
Step 3: We consider the new divisor 729 and the new remainder 362, and apply the division lemma to get
729 = 362 x 2 + 5
We consider the new divisor 362 and the new remainder 5,and apply the division lemma to get
362 = 5 x 72 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 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 1091 and 1820 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(362,5) = HCF(729,362) = HCF(1091,729) = HCF(1820,1091) .
