HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 868, 7045 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 868, 7045 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 868, 7045 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 868, 7045 is 1.
HCF(868, 7045) = 1
HCF of 868, 7045 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 868, 7045 is 1.
Highest Common Factor of 868,7045 is 1
Step 1: Since 7045 > 868, we apply the division lemma to 7045 and 868, to get
7045 = 868 x 8 + 101
Step 2: Since the reminder 868 ≠ 0, we apply division lemma to 101 and 868, to get
868 = 101 x 8 + 60
Step 3: We consider the new divisor 101 and the new remainder 60, and apply the division lemma to get
101 = 60 x 1 + 41
We consider the new divisor 60 and the new remainder 41,and apply the division lemma to get
60 = 41 x 1 + 19
We consider the new divisor 41 and the new remainder 19,and apply the division lemma to get
41 = 19 x 2 + 3
We consider the new divisor 19 and the new remainder 3,and apply the division lemma to get
19 = 3 x 6 + 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 868 and 7045 is 1
Notice that 1 = HCF(3,1) = HCF(19,3) = HCF(41,19) = HCF(60,41) = HCF(101,60) = HCF(868,101) = HCF(7045,868) .
