HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 670, 199, 747, 674 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 670, 199, 747, 674 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 670, 199, 747, 674 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 670, 199, 747, 674 is 1.
HCF(670, 199, 747, 674) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 670, 199, 747, 674 is 1.
Step 1: Since 670 > 199, we apply the division lemma to 670 and 199, to get
670 = 199 x 3 + 73
Step 2: Since the reminder 199 ≠ 0, we apply division lemma to 73 and 199, to get
199 = 73 x 2 + 53
Step 3: We consider the new divisor 73 and the new remainder 53, and apply the division lemma to get
73 = 53 x 1 + 20
We consider the new divisor 53 and the new remainder 20,and apply the division lemma to get
53 = 20 x 2 + 13
We consider the new divisor 20 and the new remainder 13,and apply the division lemma to get
20 = 13 x 1 + 7
We consider the new divisor 13 and the new remainder 7,and apply the division lemma to get
13 = 7 x 1 + 6
We consider the new divisor 7 and the new remainder 6,and apply the division lemma to get
7 = 6 x 1 + 1
We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 670 and 199 is 1
Notice that 1 = HCF(6,1) = HCF(7,6) = HCF(13,7) = HCF(20,13) = HCF(53,20) = HCF(73,53) = HCF(199,73) = HCF(670,199) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 747 > 1, we apply the division lemma to 747 and 1, to get
747 = 1 x 747 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 747 is 1
Notice that 1 = HCF(747,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 674 > 1, we apply the division lemma to 674 and 1, to get
674 = 1 x 674 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 674 is 1
Notice that 1 = HCF(674,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
