HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 898, 665, 761, 91 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 898, 665, 761, 91 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 898, 665, 761, 91 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 898, 665, 761, 91 is 1.
HCF(898, 665, 761, 91) = 1
HCF of 898, 665, 761, 91 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 898, 665, 761, 91 is 1.
Highest Common Factor of 898,665,761,91 is 1
Step 1: Since 898 > 665, we apply the division lemma to 898 and 665, to get
898 = 665 x 1 + 233
Step 2: Since the reminder 665 ≠ 0, we apply division lemma to 233 and 665, to get
665 = 233 x 2 + 199
Step 3: We consider the new divisor 233 and the new remainder 199, and apply the division lemma to get
233 = 199 x 1 + 34
We consider the new divisor 199 and the new remainder 34,and apply the division lemma to get
199 = 34 x 5 + 29
We consider the new divisor 34 and the new remainder 29,and apply the division lemma to get
34 = 29 x 1 + 5
We consider the new divisor 29 and the new remainder 5,and apply the division lemma to get
29 = 5 x 5 + 4
We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get
5 = 4 x 1 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 898 and 665 is 1
Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(29,5) = HCF(34,29) = HCF(199,34) = HCF(233,199) = HCF(665,233) = HCF(898,665) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 761 > 1, we apply the division lemma to 761 and 1, to get
761 = 1 x 761 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 761 is 1
Notice that 1 = HCF(761,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 91 > 1, we apply the division lemma to 91 and 1, to get
91 = 1 x 91 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 91 is 1
Notice that 1 = HCF(91,1) .
