HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 252, 651, 344 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 252, 651, 344 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 252, 651, 344 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 252, 651, 344 is 1.
HCF(252, 651, 344) = 1
HCF of 252, 651, 344 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 252, 651, 344 is 1.
Highest Common Factor of 252,651,344 is 1
Step 1: Since 651 > 252, we apply the division lemma to 651 and 252, to get
651 = 252 x 2 + 147
Step 2: Since the reminder 252 ≠ 0, we apply division lemma to 147 and 252, to get
252 = 147 x 1 + 105
Step 3: We consider the new divisor 147 and the new remainder 105, and apply the division lemma to get
147 = 105 x 1 + 42
We consider the new divisor 105 and the new remainder 42,and apply the division lemma to get
105 = 42 x 2 + 21
We consider the new divisor 42 and the new remainder 21,and apply the division lemma to get
42 = 21 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 21, the HCF of 252 and 651 is 21
Notice that 21 = HCF(42,21) = HCF(105,42) = HCF(147,105) = HCF(252,147) = HCF(651,252) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 344 > 21, we apply the division lemma to 344 and 21, to get
344 = 21 x 16 + 8
Step 2: Since the reminder 21 ≠ 0, we apply division lemma to 8 and 21, to get
21 = 8 x 2 + 5
Step 3: We consider the new divisor 8 and the new remainder 5, and apply the division lemma to get
8 = 5 x 1 + 3
We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get
5 = 3 x 1 + 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 21 and 344 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(8,5) = HCF(21,8) = HCF(344,21) .
