HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 13, 207, 658, 790 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 13, 207, 658, 790 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 13, 207, 658, 790 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 13, 207, 658, 790 is 1.
HCF(13, 207, 658, 790) = 1
HCF of 13, 207, 658, 790 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 13, 207, 658, 790 is 1.
Highest Common Factor of 13,207,658,790 is 1
Step 1: Since 207 > 13, we apply the division lemma to 207 and 13, to get
207 = 13 x 15 + 12
Step 2: Since the reminder 13 ≠ 0, we apply division lemma to 12 and 13, to get
13 = 12 x 1 + 1
Step 3: We consider the new divisor 12 and the new remainder 1, and apply the division lemma to get
12 = 1 x 12 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 13 and 207 is 1
Notice that 1 = HCF(12,1) = HCF(13,12) = HCF(207,13) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 658 > 1, we apply the division lemma to 658 and 1, to get
658 = 1 x 658 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 658 is 1
Notice that 1 = HCF(658,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 790 > 1, we apply the division lemma to 790 and 1, to get
790 = 1 x 790 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 790 is 1
Notice that 1 = HCF(790,1) .
