HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 581, 779, 156, 80 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 581, 779, 156, 80 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 581, 779, 156, 80 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 581, 779, 156, 80 is 1.
HCF(581, 779, 156, 80) = 1
HCF of 581, 779, 156, 80 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 581, 779, 156, 80 is 1.
Highest Common Factor of 581,779,156,80 is 1
Step 1: Since 779 > 581, we apply the division lemma to 779 and 581, to get
779 = 581 x 1 + 198
Step 2: Since the reminder 581 ≠ 0, we apply division lemma to 198 and 581, to get
581 = 198 x 2 + 185
Step 3: We consider the new divisor 198 and the new remainder 185, and apply the division lemma to get
198 = 185 x 1 + 13
We consider the new divisor 185 and the new remainder 13,and apply the division lemma to get
185 = 13 x 14 + 3
We consider the new divisor 13 and the new remainder 3,and apply the division lemma to get
13 = 3 x 4 + 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 581 and 779 is 1
Notice that 1 = HCF(3,1) = HCF(13,3) = HCF(185,13) = HCF(198,185) = HCF(581,198) = HCF(779,581) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 156 > 1, we apply the division lemma to 156 and 1, to get
156 = 1 x 156 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 156 is 1
Notice that 1 = HCF(156,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 80 > 1, we apply the division lemma to 80 and 1, to get
80 = 1 x 80 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 80 is 1
Notice that 1 = HCF(80,1) .
