HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 44, 57, 90, 641 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 44, 57, 90, 641 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 44, 57, 90, 641 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 44, 57, 90, 641 is 1.
HCF(44, 57, 90, 641) = 1
HCF of 44, 57, 90, 641 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 44, 57, 90, 641 is 1.
Highest Common Factor of 44,57,90,641 is 1
Step 1: Since 57 > 44, we apply the division lemma to 57 and 44, to get
57 = 44 x 1 + 13
Step 2: Since the reminder 44 ≠ 0, we apply division lemma to 13 and 44, to get
44 = 13 x 3 + 5
Step 3: We consider the new divisor 13 and the new remainder 5, and apply the division lemma to get
13 = 5 x 2 + 3
We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get
5 = 3 x 1 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 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 44 and 57 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(13,5) = HCF(44,13) = HCF(57,44) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 90 > 1, we apply the division lemma to 90 and 1, to get
90 = 1 x 90 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 90 is 1
Notice that 1 = HCF(90,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 641 > 1, we apply the division lemma to 641 and 1, to get
641 = 1 x 641 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 641 is 1
Notice that 1 = HCF(641,1) .
