HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 651, 278, 939 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 651, 278, 939 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, 278, 939 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, 278, 939 is 1.
HCF(651, 278, 939) = 1
HCF of 651, 278, 939 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, 278, 939 is 1.
Highest Common Factor of 651,278,939 is 1
Step 1: Since 651 > 278, we apply the division lemma to 651 and 278, to get
651 = 278 x 2 + 95
Step 2: Since the reminder 278 ≠ 0, we apply division lemma to 95 and 278, to get
278 = 95 x 2 + 88
Step 3: We consider the new divisor 95 and the new remainder 88, and apply the division lemma to get
95 = 88 x 1 + 7
We consider the new divisor 88 and the new remainder 7,and apply the division lemma to get
88 = 7 x 12 + 4
We consider the new divisor 7 and the new remainder 4,and apply the division lemma to get
7 = 4 x 1 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 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 651 and 278 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(88,7) = HCF(95,88) = HCF(278,95) = HCF(651,278) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 939 > 1, we apply the division lemma to 939 and 1, to get
939 = 1 x 939 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 939 is 1
Notice that 1 = HCF(939,1) .
