HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 440, 679 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 440, 679 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 440, 679 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 440, 679 is 1.
HCF(440, 679) = 1
HCF of 440, 679 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 440, 679 is 1.
Highest Common Factor of 440,679 is 1
Step 1: Since 679 > 440, we apply the division lemma to 679 and 440, to get
679 = 440 x 1 + 239
Step 2: Since the reminder 440 ≠ 0, we apply division lemma to 239 and 440, to get
440 = 239 x 1 + 201
Step 3: We consider the new divisor 239 and the new remainder 201, and apply the division lemma to get
239 = 201 x 1 + 38
We consider the new divisor 201 and the new remainder 38,and apply the division lemma to get
201 = 38 x 5 + 11
We consider the new divisor 38 and the new remainder 11,and apply the division lemma to get
38 = 11 x 3 + 5
We consider the new divisor 11 and the new remainder 5,and apply the division lemma to get
11 = 5 x 2 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 440 and 679 is 1
Notice that 1 = HCF(5,1) = HCF(11,5) = HCF(38,11) = HCF(201,38) = HCF(239,201) = HCF(440,239) = HCF(679,440) .
