HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 791, 636, 580 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 791, 636, 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 791, 636, 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 791, 636, 580 is 1.
HCF(791, 636, 580) = 1
HCF of 791, 636, 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 791, 636, 580 is 1.
Highest Common Factor of 791,636,580 is 1
Step 1: Since 791 > 636, we apply the division lemma to 791 and 636, to get
791 = 636 x 1 + 155
Step 2: Since the reminder 636 ≠ 0, we apply division lemma to 155 and 636, to get
636 = 155 x 4 + 16
Step 3: We consider the new divisor 155 and the new remainder 16, and apply the division lemma to get
155 = 16 x 9 + 11
We consider the new divisor 16 and the new remainder 11,and apply the division lemma to get
16 = 11 x 1 + 5
We consider the new divisor 11 and the new remainder 5,and apply the division lemma to get
11 = 5 x 2 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 791 and 636 is 1
Notice that 1 = HCF(5,1) = HCF(11,5) = HCF(16,11) = HCF(155,16) = HCF(636,155) = HCF(791,636) .
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) .
