HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 647, 532, 430 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 647, 532, 430 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 647, 532, 430 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 647, 532, 430 is 1.
HCF(647, 532, 430) = 1
HCF of 647, 532, 430 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 647, 532, 430 is 1.
Highest Common Factor of 647,532,430 is 1
Step 1: Since 647 > 532, we apply the division lemma to 647 and 532, to get
647 = 532 x 1 + 115
Step 2: Since the reminder 532 ≠ 0, we apply division lemma to 115 and 532, to get
532 = 115 x 4 + 72
Step 3: We consider the new divisor 115 and the new remainder 72, and apply the division lemma to get
115 = 72 x 1 + 43
We consider the new divisor 72 and the new remainder 43,and apply the division lemma to get
72 = 43 x 1 + 29
We consider the new divisor 43 and the new remainder 29,and apply the division lemma to get
43 = 29 x 1 + 14
We consider the new divisor 29 and the new remainder 14,and apply the division lemma to get
29 = 14 x 2 + 1
We consider the new divisor 14 and the new remainder 1,and apply the division lemma to get
14 = 1 x 14 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 647 and 532 is 1
Notice that 1 = HCF(14,1) = HCF(29,14) = HCF(43,29) = HCF(72,43) = HCF(115,72) = HCF(532,115) = HCF(647,532) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 430 > 1, we apply the division lemma to 430 and 1, to get
430 = 1 x 430 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 430 is 1
Notice that 1 = HCF(430,1) .
