HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 918, 391, 928, 581 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 918, 391, 928, 581 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 918, 391, 928, 581 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 918, 391, 928, 581 is 1.
HCF(918, 391, 928, 581) = 1
HCF of 918, 391, 928, 581 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 918, 391, 928, 581 is 1.
Highest Common Factor of 918,391,928,581 is 1
Step 1: Since 918 > 391, we apply the division lemma to 918 and 391, to get
918 = 391 x 2 + 136
Step 2: Since the reminder 391 ≠ 0, we apply division lemma to 136 and 391, to get
391 = 136 x 2 + 119
Step 3: We consider the new divisor 136 and the new remainder 119, and apply the division lemma to get
136 = 119 x 1 + 17
We consider the new divisor 119 and the new remainder 17, and apply the division lemma to get
119 = 17 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 17, the HCF of 918 and 391 is 17
Notice that 17 = HCF(119,17) = HCF(136,119) = HCF(391,136) = HCF(918,391) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 928 > 17, we apply the division lemma to 928 and 17, to get
928 = 17 x 54 + 10
Step 2: Since the reminder 17 ≠ 0, we apply division lemma to 10 and 17, to get
17 = 10 x 1 + 7
Step 3: We consider the new divisor 10 and the new remainder 7, and apply the division lemma to get
10 = 7 x 1 + 3
We consider the new divisor 7 and the new remainder 3,and apply the division lemma to get
7 = 3 x 2 + 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 17 and 928 is 1
Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(10,7) = HCF(17,10) = HCF(928,17) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 581 > 1, we apply the division lemma to 581 and 1, to get
581 = 1 x 581 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 581 is 1
Notice that 1 = HCF(581,1) .
