HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 679, 917, 268 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 679, 917, 268 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 679, 917, 268 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 679, 917, 268 is 1.
HCF(679, 917, 268) = 1
HCF of 679, 917, 268 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 679, 917, 268 is 1.
Highest Common Factor of 679,917,268 is 1
Step 1: Since 917 > 679, we apply the division lemma to 917 and 679, to get
917 = 679 x 1 + 238
Step 2: Since the reminder 679 ≠ 0, we apply division lemma to 238 and 679, to get
679 = 238 x 2 + 203
Step 3: We consider the new divisor 238 and the new remainder 203, and apply the division lemma to get
238 = 203 x 1 + 35
We consider the new divisor 203 and the new remainder 35,and apply the division lemma to get
203 = 35 x 5 + 28
We consider the new divisor 35 and the new remainder 28,and apply the division lemma to get
35 = 28 x 1 + 7
We consider the new divisor 28 and the new remainder 7,and apply the division lemma to get
28 = 7 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 679 and 917 is 7
Notice that 7 = HCF(28,7) = HCF(35,28) = HCF(203,35) = HCF(238,203) = HCF(679,238) = HCF(917,679) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 268 > 7, we apply the division lemma to 268 and 7, to get
268 = 7 x 38 + 2
Step 2: Since the reminder 7 ≠ 0, we apply division lemma to 2 and 7, to get
7 = 2 x 3 + 1
Step 3: 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 7 and 268 is 1
Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(268,7) .
