HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 207, 1798 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 207, 1798 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 207, 1798 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 207, 1798 is 1.
HCF(207, 1798) = 1
HCF of 207, 1798 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 207, 1798 is 1.
Highest Common Factor of 207,1798 is 1
Step 1: Since 1798 > 207, we apply the division lemma to 1798 and 207, to get
1798 = 207 x 8 + 142
Step 2: Since the reminder 207 ≠ 0, we apply division lemma to 142 and 207, to get
207 = 142 x 1 + 65
Step 3: We consider the new divisor 142 and the new remainder 65, and apply the division lemma to get
142 = 65 x 2 + 12
We consider the new divisor 65 and the new remainder 12,and apply the division lemma to get
65 = 12 x 5 + 5
We consider the new divisor 12 and the new remainder 5,and apply the division lemma to get
12 = 5 x 2 + 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 207 and 1798 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(12,5) = HCF(65,12) = HCF(142,65) = HCF(207,142) = HCF(1798,207) .
