HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 268, 437 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 268, 437 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, 437 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, 437 is 1.
HCF(268, 437) = 1
HCF of 268, 437 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, 437 is 1.
Highest Common Factor of 268,437 is 1
Step 1: Since 437 > 268, we apply the division lemma to 437 and 268, to get
437 = 268 x 1 + 169
Step 2: Since the reminder 268 ≠ 0, we apply division lemma to 169 and 268, to get
268 = 169 x 1 + 99
Step 3: We consider the new divisor 169 and the new remainder 99, and apply the division lemma to get
169 = 99 x 1 + 70
We consider the new divisor 99 and the new remainder 70,and apply the division lemma to get
99 = 70 x 1 + 29
We consider the new divisor 70 and the new remainder 29,and apply the division lemma to get
70 = 29 x 2 + 12
We consider the new divisor 29 and the new remainder 12,and apply the division lemma to get
29 = 12 x 2 + 5
We consider the new divisor 12 and the new remainder 5,and apply the division lemma to get
12 = 5 x 2 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 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 268 and 437 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(12,5) = HCF(29,12) = HCF(70,29) = HCF(99,70) = HCF(169,99) = HCF(268,169) = HCF(437,268) .
