HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 430, 697, 283 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 430, 697, 283 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 430, 697, 283 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 430, 697, 283 is 1.
HCF(430, 697, 283) = 1
HCF of 430, 697, 283 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 430, 697, 283 is 1.
Highest Common Factor of 430,697,283 is 1
Step 1: Since 697 > 430, we apply the division lemma to 697 and 430, to get
697 = 430 x 1 + 267
Step 2: Since the reminder 430 ≠ 0, we apply division lemma to 267 and 430, to get
430 = 267 x 1 + 163
Step 3: We consider the new divisor 267 and the new remainder 163, and apply the division lemma to get
267 = 163 x 1 + 104
We consider the new divisor 163 and the new remainder 104,and apply the division lemma to get
163 = 104 x 1 + 59
We consider the new divisor 104 and the new remainder 59,and apply the division lemma to get
104 = 59 x 1 + 45
We consider the new divisor 59 and the new remainder 45,and apply the division lemma to get
59 = 45 x 1 + 14
We consider the new divisor 45 and the new remainder 14,and apply the division lemma to get
45 = 14 x 3 + 3
We consider the new divisor 14 and the new remainder 3,and apply the division lemma to get
14 = 3 x 4 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 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 430 and 697 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(14,3) = HCF(45,14) = HCF(59,45) = HCF(104,59) = HCF(163,104) = HCF(267,163) = HCF(430,267) = HCF(697,430) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 283 > 1, we apply the division lemma to 283 and 1, to get
283 = 1 x 283 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 283 is 1
Notice that 1 = HCF(283,1) .
