HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 479, 764, 890 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 479, 764, 890 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 479, 764, 890 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 479, 764, 890 is 1.
HCF(479, 764, 890) = 1
HCF of 479, 764, 890 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 479, 764, 890 is 1.
Highest Common Factor of 479,764,890 is 1
Step 1: Since 764 > 479, we apply the division lemma to 764 and 479, to get
764 = 479 x 1 + 285
Step 2: Since the reminder 479 ≠ 0, we apply division lemma to 285 and 479, to get
479 = 285 x 1 + 194
Step 3: We consider the new divisor 285 and the new remainder 194, and apply the division lemma to get
285 = 194 x 1 + 91
We consider the new divisor 194 and the new remainder 91,and apply the division lemma to get
194 = 91 x 2 + 12
We consider the new divisor 91 and the new remainder 12,and apply the division lemma to get
91 = 12 x 7 + 7
We consider the new divisor 12 and the new remainder 7,and apply the division lemma to get
12 = 7 x 1 + 5
We consider the new divisor 7 and the new remainder 5,and apply the division lemma to get
7 = 5 x 1 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 479 and 764 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(7,5) = HCF(12,7) = HCF(91,12) = HCF(194,91) = HCF(285,194) = HCF(479,285) = HCF(764,479) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 890 > 1, we apply the division lemma to 890 and 1, to get
890 = 1 x 890 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 890 is 1
Notice that 1 = HCF(890,1) .
