HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 268, 108, 251, 100 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 268, 108, 251, 100 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 268, 108, 251, 100 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 268, 108, 251, 100 is 1.
HCF(268, 108, 251, 100) = 1
HCF of 268, 108, 251, 100 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 268, 108, 251, 100 is 1.
Highest Common Factor of 268,108,251,100 is 1
Step 1: Since 268 > 108, we apply the division lemma to 268 and 108, to get
268 = 108 x 2 + 52
Step 2: Since the reminder 108 ≠ 0, we apply division lemma to 52 and 108, to get
108 = 52 x 2 + 4
Step 3: We consider the new divisor 52 and the new remainder 4, and apply the division lemma to get
52 = 4 x 13 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 268 and 108 is 4
Notice that 4 = HCF(52,4) = HCF(108,52) = HCF(268,108) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 251 > 4, we apply the division lemma to 251 and 4, to get
251 = 4 x 62 + 3
Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 3 and 4, to get
4 = 3 x 1 + 1
Step 3: 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 4 and 251 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(251,4) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 100 > 1, we apply the division lemma to 100 and 1, to get
100 = 1 x 100 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 100 is 1
Notice that 1 = HCF(100,1) .
