HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 679, 429 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 679, 429 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, 429 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, 429 is 1.
HCF(679, 429) = 1
HCF of 679, 429 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, 429 is 1.
Highest Common Factor of 679,429 is 1
Step 1: Since 679 > 429, we apply the division lemma to 679 and 429, to get
679 = 429 x 1 + 250
Step 2: Since the reminder 429 ≠ 0, we apply division lemma to 250 and 429, to get
429 = 250 x 1 + 179
Step 3: We consider the new divisor 250 and the new remainder 179, and apply the division lemma to get
250 = 179 x 1 + 71
We consider the new divisor 179 and the new remainder 71,and apply the division lemma to get
179 = 71 x 2 + 37
We consider the new divisor 71 and the new remainder 37,and apply the division lemma to get
71 = 37 x 1 + 34
We consider the new divisor 37 and the new remainder 34,and apply the division lemma to get
37 = 34 x 1 + 3
We consider the new divisor 34 and the new remainder 3,and apply the division lemma to get
34 = 3 x 11 + 1
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 679 and 429 is 1
Notice that 1 = HCF(3,1) = HCF(34,3) = HCF(37,34) = HCF(71,37) = HCF(179,71) = HCF(250,179) = HCF(429,250) = HCF(679,429) .
