HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 612, 991, 346 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 612, 991, 346 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 612, 991, 346 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 612, 991, 346 is 1.
HCF(612, 991, 346) = 1
HCF of 612, 991, 346 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 612, 991, 346 is 1.
Highest Common Factor of 612,991,346 is 1
Step 1: Since 991 > 612, we apply the division lemma to 991 and 612, to get
991 = 612 x 1 + 379
Step 2: Since the reminder 612 ≠ 0, we apply division lemma to 379 and 612, to get
612 = 379 x 1 + 233
Step 3: We consider the new divisor 379 and the new remainder 233, and apply the division lemma to get
379 = 233 x 1 + 146
We consider the new divisor 233 and the new remainder 146,and apply the division lemma to get
233 = 146 x 1 + 87
We consider the new divisor 146 and the new remainder 87,and apply the division lemma to get
146 = 87 x 1 + 59
We consider the new divisor 87 and the new remainder 59,and apply the division lemma to get
87 = 59 x 1 + 28
We consider the new divisor 59 and the new remainder 28,and apply the division lemma to get
59 = 28 x 2 + 3
We consider the new divisor 28 and the new remainder 3,and apply the division lemma to get
28 = 3 x 9 + 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 612 and 991 is 1
Notice that 1 = HCF(3,1) = HCF(28,3) = HCF(59,28) = HCF(87,59) = HCF(146,87) = HCF(233,146) = HCF(379,233) = HCF(612,379) = HCF(991,612) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 346 > 1, we apply the division lemma to 346 and 1, to get
346 = 1 x 346 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 346 is 1
Notice that 1 = HCF(346,1) .
