HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 701, 479, 72 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 701, 479, 72 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 701, 479, 72 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 701, 479, 72 is 1.
HCF(701, 479, 72) = 1
HCF of 701, 479, 72 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 701, 479, 72 is 1.
Highest Common Factor of 701,479,72 is 1
Step 1: Since 701 > 479, we apply the division lemma to 701 and 479, to get
701 = 479 x 1 + 222
Step 2: Since the reminder 479 ≠ 0, we apply division lemma to 222 and 479, to get
479 = 222 x 2 + 35
Step 3: We consider the new divisor 222 and the new remainder 35, and apply the division lemma to get
222 = 35 x 6 + 12
We consider the new divisor 35 and the new remainder 12,and apply the division lemma to get
35 = 12 x 2 + 11
We consider the new divisor 12 and the new remainder 11,and apply the division lemma to get
12 = 11 x 1 + 1
We consider the new divisor 11 and the new remainder 1,and apply the division lemma to get
11 = 1 x 11 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 701 and 479 is 1
Notice that 1 = HCF(11,1) = HCF(12,11) = HCF(35,12) = HCF(222,35) = HCF(479,222) = HCF(701,479) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 72 > 1, we apply the division lemma to 72 and 1, to get
72 = 1 x 72 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 72 is 1
Notice that 1 = HCF(72,1) .
