HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 779, 981, 580 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 779, 981, 580 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 779, 981, 580 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 779, 981, 580 is 1.
HCF(779, 981, 580) = 1
HCF of 779, 981, 580 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 779, 981, 580 is 1.
Highest Common Factor of 779,981,580 is 1
Step 1: Since 981 > 779, we apply the division lemma to 981 and 779, to get
981 = 779 x 1 + 202
Step 2: Since the reminder 779 ≠ 0, we apply division lemma to 202 and 779, to get
779 = 202 x 3 + 173
Step 3: We consider the new divisor 202 and the new remainder 173, and apply the division lemma to get
202 = 173 x 1 + 29
We consider the new divisor 173 and the new remainder 29,and apply the division lemma to get
173 = 29 x 5 + 28
We consider the new divisor 29 and the new remainder 28,and apply the division lemma to get
29 = 28 x 1 + 1
We consider the new divisor 28 and the new remainder 1,and apply the division lemma to get
28 = 1 x 28 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 779 and 981 is 1
Notice that 1 = HCF(28,1) = HCF(29,28) = HCF(173,29) = HCF(202,173) = HCF(779,202) = HCF(981,779) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 580 > 1, we apply the division lemma to 580 and 1, to get
580 = 1 x 580 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 580 is 1
Notice that 1 = HCF(580,1) .
