HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 278, 734, 706 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 278, 734, 706 is 2 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 278, 734, 706 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 278, 734, 706 is 2.
HCF(278, 734, 706) = 2
HCF of 278, 734, 706 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 278, 734, 706 is 2.
Highest Common Factor of 278,734,706 is 2
Step 1: Since 734 > 278, we apply the division lemma to 734 and 278, to get
734 = 278 x 2 + 178
Step 2: Since the reminder 278 ≠ 0, we apply division lemma to 178 and 278, to get
278 = 178 x 1 + 100
Step 3: We consider the new divisor 178 and the new remainder 100, and apply the division lemma to get
178 = 100 x 1 + 78
We consider the new divisor 100 and the new remainder 78,and apply the division lemma to get
100 = 78 x 1 + 22
We consider the new divisor 78 and the new remainder 22,and apply the division lemma to get
78 = 22 x 3 + 12
We consider the new divisor 22 and the new remainder 12,and apply the division lemma to get
22 = 12 x 1 + 10
We consider the new divisor 12 and the new remainder 10,and apply the division lemma to get
12 = 10 x 1 + 2
We consider the new divisor 10 and the new remainder 2,and apply the division lemma to get
10 = 2 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 278 and 734 is 2
Notice that 2 = HCF(10,2) = HCF(12,10) = HCF(22,12) = HCF(78,22) = HCF(100,78) = HCF(178,100) = HCF(278,178) = HCF(734,278) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 706 > 2, we apply the division lemma to 706 and 2, to get
706 = 2 x 353 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 706 is 2
Notice that 2 = HCF(706,2) .
