HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 147, 391, 699 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 147, 391, 699 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 147, 391, 699 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 147, 391, 699 is 1.
HCF(147, 391, 699) = 1
HCF of 147, 391, 699 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 147, 391, 699 is 1.
Highest Common Factor of 147,391,699 is 1
Step 1: Since 391 > 147, we apply the division lemma to 391 and 147, to get
391 = 147 x 2 + 97
Step 2: Since the reminder 147 ≠ 0, we apply division lemma to 97 and 147, to get
147 = 97 x 1 + 50
Step 3: We consider the new divisor 97 and the new remainder 50, and apply the division lemma to get
97 = 50 x 1 + 47
We consider the new divisor 50 and the new remainder 47,and apply the division lemma to get
50 = 47 x 1 + 3
We consider the new divisor 47 and the new remainder 3,and apply the division lemma to get
47 = 3 x 15 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 147 and 391 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(47,3) = HCF(50,47) = HCF(97,50) = HCF(147,97) = HCF(391,147) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 699 > 1, we apply the division lemma to 699 and 1, to get
699 = 1 x 699 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 699 is 1
Notice that 1 = HCF(699,1) .
