HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 683, 429, 768 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 683, 429, 768 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 683, 429, 768 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 683, 429, 768 is 1.
HCF(683, 429, 768) = 1
HCF of 683, 429, 768 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 683, 429, 768 is 1.
Highest Common Factor of 683,429,768 is 1
Step 1: Since 683 > 429, we apply the division lemma to 683 and 429, to get
683 = 429 x 1 + 254
Step 2: Since the reminder 429 ≠ 0, we apply division lemma to 254 and 429, to get
429 = 254 x 1 + 175
Step 3: We consider the new divisor 254 and the new remainder 175, and apply the division lemma to get
254 = 175 x 1 + 79
We consider the new divisor 175 and the new remainder 79,and apply the division lemma to get
175 = 79 x 2 + 17
We consider the new divisor 79 and the new remainder 17,and apply the division lemma to get
79 = 17 x 4 + 11
We consider the new divisor 17 and the new remainder 11,and apply the division lemma to get
17 = 11 x 1 + 6
We consider the new divisor 11 and the new remainder 6,and apply the division lemma to get
11 = 6 x 1 + 5
We consider the new divisor 6 and the new remainder 5,and apply the division lemma to get
6 = 5 x 1 + 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 683 and 429 is 1
Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(11,6) = HCF(17,11) = HCF(79,17) = HCF(175,79) = HCF(254,175) = HCF(429,254) = HCF(683,429) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 768 > 1, we apply the division lemma to 768 and 1, to get
768 = 1 x 768 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 768 is 1
Notice that 1 = HCF(768,1) .
