HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 651, 766, 611, 15 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 651, 766, 611, 15 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 651, 766, 611, 15 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 651, 766, 611, 15 is 1.
HCF(651, 766, 611, 15) = 1
HCF of 651, 766, 611, 15 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 651, 766, 611, 15 is 1.
Highest Common Factor of 651,766,611,15 is 1
Step 1: Since 766 > 651, we apply the division lemma to 766 and 651, to get
766 = 651 x 1 + 115
Step 2: Since the reminder 651 ≠ 0, we apply division lemma to 115 and 651, to get
651 = 115 x 5 + 76
Step 3: We consider the new divisor 115 and the new remainder 76, and apply the division lemma to get
115 = 76 x 1 + 39
We consider the new divisor 76 and the new remainder 39,and apply the division lemma to get
76 = 39 x 1 + 37
We consider the new divisor 39 and the new remainder 37,and apply the division lemma to get
39 = 37 x 1 + 2
We consider the new divisor 37 and the new remainder 2,and apply the division lemma to get
37 = 2 x 18 + 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 651 and 766 is 1
Notice that 1 = HCF(2,1) = HCF(37,2) = HCF(39,37) = HCF(76,39) = HCF(115,76) = HCF(651,115) = HCF(766,651) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 611 > 1, we apply the division lemma to 611 and 1, to get
611 = 1 x 611 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 611 is 1
Notice that 1 = HCF(611,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 15 > 1, we apply the division lemma to 15 and 1, to get
15 = 1 x 15 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 15 is 1
Notice that 1 = HCF(15,1) .
