HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 7245, 7874, 66642 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 7245, 7874, 66642 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 7245, 7874, 66642 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 7245, 7874, 66642 is 1.
HCF(7245, 7874, 66642) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 7245, 7874, 66642 is 1.
Step 1: Since 7874 > 7245, we apply the division lemma to 7874 and 7245, to get
7874 = 7245 x 1 + 629
Step 2: Since the reminder 7245 ≠ 0, we apply division lemma to 629 and 7245, to get
7245 = 629 x 11 + 326
Step 3: We consider the new divisor 629 and the new remainder 326, and apply the division lemma to get
629 = 326 x 1 + 303
We consider the new divisor 326 and the new remainder 303,and apply the division lemma to get
326 = 303 x 1 + 23
We consider the new divisor 303 and the new remainder 23,and apply the division lemma to get
303 = 23 x 13 + 4
We consider the new divisor 23 and the new remainder 4,and apply the division lemma to get
23 = 4 x 5 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 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 7245 and 7874 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(23,4) = HCF(303,23) = HCF(326,303) = HCF(629,326) = HCF(7245,629) = HCF(7874,7245) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 66642 > 1, we apply the division lemma to 66642 and 1, to get
66642 = 1 x 66642 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 66642 is 1
Notice that 1 = HCF(66642,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?
