HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 666, 853 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 666, 853 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 666, 853 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 666, 853 is 1.
HCF(666, 853) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 666, 853 is 1.
Step 1: Since 853 > 666, we apply the division lemma to 853 and 666, to get
853 = 666 x 1 + 187
Step 2: Since the reminder 666 ≠ 0, we apply division lemma to 187 and 666, to get
666 = 187 x 3 + 105
Step 3: We consider the new divisor 187 and the new remainder 105, and apply the division lemma to get
187 = 105 x 1 + 82
We consider the new divisor 105 and the new remainder 82,and apply the division lemma to get
105 = 82 x 1 + 23
We consider the new divisor 82 and the new remainder 23,and apply the division lemma to get
82 = 23 x 3 + 13
We consider the new divisor 23 and the new remainder 13,and apply the division lemma to get
23 = 13 x 1 + 10
We consider the new divisor 13 and the new remainder 10,and apply the division lemma to get
13 = 10 x 1 + 3
We consider the new divisor 10 and the new remainder 3,and apply the division lemma to get
10 = 3 x 3 + 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 666 and 853 is 1
Notice that 1 = HCF(3,1) = HCF(10,3) = HCF(13,10) = HCF(23,13) = HCF(82,23) = HCF(105,82) = HCF(187,105) = HCF(666,187) = HCF(853,666) .
Here are some samples of HCF using Euclid's Algorithm calculations.
