HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 56, 765, 441, 665 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 56, 765, 441, 665 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 56, 765, 441, 665 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 56, 765, 441, 665 is 1.
HCF(56, 765, 441, 665) = 1
HCF of 56, 765, 441, 665 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 56, 765, 441, 665 is 1.
Highest Common Factor of 56,765,441,665 is 1
Step 1: Since 765 > 56, we apply the division lemma to 765 and 56, to get
765 = 56 x 13 + 37
Step 2: Since the reminder 56 ≠ 0, we apply division lemma to 37 and 56, to get
56 = 37 x 1 + 19
Step 3: We consider the new divisor 37 and the new remainder 19, and apply the division lemma to get
37 = 19 x 1 + 18
We consider the new divisor 19 and the new remainder 18,and apply the division lemma to get
19 = 18 x 1 + 1
We consider the new divisor 18 and the new remainder 1,and apply the division lemma to get
18 = 1 x 18 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 56 and 765 is 1
Notice that 1 = HCF(18,1) = HCF(19,18) = HCF(37,19) = HCF(56,37) = HCF(765,56) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 441 > 1, we apply the division lemma to 441 and 1, to get
441 = 1 x 441 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 441 is 1
Notice that 1 = HCF(441,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 665 > 1, we apply the division lemma to 665 and 1, to get
665 = 1 x 665 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 665 is 1
Notice that 1 = HCF(665,1) .
