HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 756, 414, 479 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 756, 414, 479 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 756, 414, 479 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 756, 414, 479 is 1.
HCF(756, 414, 479) = 1
HCF of 756, 414, 479 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 756, 414, 479 is 1.
Highest Common Factor of 756,414,479 is 1
Step 1: Since 756 > 414, we apply the division lemma to 756 and 414, to get
756 = 414 x 1 + 342
Step 2: Since the reminder 414 ≠ 0, we apply division lemma to 342 and 414, to get
414 = 342 x 1 + 72
Step 3: We consider the new divisor 342 and the new remainder 72, and apply the division lemma to get
342 = 72 x 4 + 54
We consider the new divisor 72 and the new remainder 54,and apply the division lemma to get
72 = 54 x 1 + 18
We consider the new divisor 54 and the new remainder 18,and apply the division lemma to get
54 = 18 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 18, the HCF of 756 and 414 is 18
Notice that 18 = HCF(54,18) = HCF(72,54) = HCF(342,72) = HCF(414,342) = HCF(756,414) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 479 > 18, we apply the division lemma to 479 and 18, to get
479 = 18 x 26 + 11
Step 2: Since the reminder 18 ≠ 0, we apply division lemma to 11 and 18, to get
18 = 11 x 1 + 7
Step 3: We consider the new divisor 11 and the new remainder 7, and apply the division lemma to get
11 = 7 x 1 + 4
We consider the new divisor 7 and the new remainder 4,and apply the division lemma to get
7 = 4 x 1 + 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 18 and 479 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(11,7) = HCF(18,11) = HCF(479,18) .
