HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 429, 1109 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 429, 1109 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 429, 1109 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 429, 1109 is 1.
HCF(429, 1109) = 1
HCF of 429, 1109 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 429, 1109 is 1.
Highest Common Factor of 429,1109 is 1
Step 1: Since 1109 > 429, we apply the division lemma to 1109 and 429, to get
1109 = 429 x 2 + 251
Step 2: Since the reminder 429 ≠ 0, we apply division lemma to 251 and 429, to get
429 = 251 x 1 + 178
Step 3: We consider the new divisor 251 and the new remainder 178, and apply the division lemma to get
251 = 178 x 1 + 73
We consider the new divisor 178 and the new remainder 73,and apply the division lemma to get
178 = 73 x 2 + 32
We consider the new divisor 73 and the new remainder 32,and apply the division lemma to get
73 = 32 x 2 + 9
We consider the new divisor 32 and the new remainder 9,and apply the division lemma to get
32 = 9 x 3 + 5
We consider the new divisor 9 and the new remainder 5,and apply the division lemma to get
9 = 5 x 1 + 4
We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get
5 = 4 x 1 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 429 and 1109 is 1
Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(9,5) = HCF(32,9) = HCF(73,32) = HCF(178,73) = HCF(251,178) = HCF(429,251) = HCF(1109,429) .
