HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 904, 7911, 1670 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 904, 7911, 1670 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 904, 7911, 1670 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 904, 7911, 1670 is 1.
HCF(904, 7911, 1670) = 1
HCF of 904, 7911, 1670 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 904, 7911, 1670 is 1.
Highest Common Factor of 904,7911,1670 is 1
Step 1: Since 7911 > 904, we apply the division lemma to 7911 and 904, to get
7911 = 904 x 8 + 679
Step 2: Since the reminder 904 ≠ 0, we apply division lemma to 679 and 904, to get
904 = 679 x 1 + 225
Step 3: We consider the new divisor 679 and the new remainder 225, and apply the division lemma to get
679 = 225 x 3 + 4
We consider the new divisor 225 and the new remainder 4,and apply the division lemma to get
225 = 4 x 56 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 904 and 7911 is 1
Notice that 1 = HCF(4,1) = HCF(225,4) = HCF(679,225) = HCF(904,679) = HCF(7911,904) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 1670 > 1, we apply the division lemma to 1670 and 1, to get
1670 = 1 x 1670 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 1670 is 1
Notice that 1 = HCF(1670,1) .
