HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 698, 429, 704 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 698, 429, 704 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 698, 429, 704 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 698, 429, 704 is 1.
HCF(698, 429, 704) = 1
HCF of 698, 429, 704 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 698, 429, 704 is 1.
Highest Common Factor of 698,429,704 is 1
Step 1: Since 698 > 429, we apply the division lemma to 698 and 429, to get
698 = 429 x 1 + 269
Step 2: Since the reminder 429 ≠ 0, we apply division lemma to 269 and 429, to get
429 = 269 x 1 + 160
Step 3: We consider the new divisor 269 and the new remainder 160, and apply the division lemma to get
269 = 160 x 1 + 109
We consider the new divisor 160 and the new remainder 109,and apply the division lemma to get
160 = 109 x 1 + 51
We consider the new divisor 109 and the new remainder 51,and apply the division lemma to get
109 = 51 x 2 + 7
We consider the new divisor 51 and the new remainder 7,and apply the division lemma to get
51 = 7 x 7 + 2
We consider the new divisor 7 and the new remainder 2,and apply the division lemma to get
7 = 2 x 3 + 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 698 and 429 is 1
Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(51,7) = HCF(109,51) = HCF(160,109) = HCF(269,160) = HCF(429,269) = HCF(698,429) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 704 > 1, we apply the division lemma to 704 and 1, to get
704 = 1 x 704 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 704 is 1
Notice that 1 = HCF(704,1) .
