HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 7021, 9000 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 7021, 9000 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 7021, 9000 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 7021, 9000 is 1.
HCF(7021, 9000) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 7021, 9000 is 1.
Step 1: Since 9000 > 7021, we apply the division lemma to 9000 and 7021, to get
9000 = 7021 x 1 + 1979
Step 2: Since the reminder 7021 ≠ 0, we apply division lemma to 1979 and 7021, to get
7021 = 1979 x 3 + 1084
Step 3: We consider the new divisor 1979 and the new remainder 1084, and apply the division lemma to get
1979 = 1084 x 1 + 895
We consider the new divisor 1084 and the new remainder 895,and apply the division lemma to get
1084 = 895 x 1 + 189
We consider the new divisor 895 and the new remainder 189,and apply the division lemma to get
895 = 189 x 4 + 139
We consider the new divisor 189 and the new remainder 139,and apply the division lemma to get
189 = 139 x 1 + 50
We consider the new divisor 139 and the new remainder 50,and apply the division lemma to get
139 = 50 x 2 + 39
We consider the new divisor 50 and the new remainder 39,and apply the division lemma to get
50 = 39 x 1 + 11
We consider the new divisor 39 and the new remainder 11,and apply the division lemma to get
39 = 11 x 3 + 6
We consider the new divisor 11 and the new remainder 6,and apply the division lemma to get
11 = 6 x 1 + 5
We consider the new divisor 6 and the new remainder 5,and apply the division lemma to get
6 = 5 x 1 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 7021 and 9000 is 1
Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(11,6) = HCF(39,11) = HCF(50,39) = HCF(139,50) = HCF(189,139) = HCF(895,189) = HCF(1084,895) = HCF(1979,1084) = HCF(7021,1979) = HCF(9000,7021) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?
