HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 494, 780, 430 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 494, 780, 430 is 2 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 494, 780, 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 494, 780, 430 is 2.
HCF(494, 780, 430) = 2
HCF of 494, 780, 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 494, 780, 430 is 2.
Highest Common Factor of 494,780,430 is 2
Step 1: Since 780 > 494, we apply the division lemma to 780 and 494, to get
780 = 494 x 1 + 286
Step 2: Since the reminder 494 ≠ 0, we apply division lemma to 286 and 494, to get
494 = 286 x 1 + 208
Step 3: We consider the new divisor 286 and the new remainder 208, and apply the division lemma to get
286 = 208 x 1 + 78
We consider the new divisor 208 and the new remainder 78,and apply the division lemma to get
208 = 78 x 2 + 52
We consider the new divisor 78 and the new remainder 52,and apply the division lemma to get
78 = 52 x 1 + 26
We consider the new divisor 52 and the new remainder 26,and apply the division lemma to get
52 = 26 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 26, the HCF of 494 and 780 is 26
Notice that 26 = HCF(52,26) = HCF(78,52) = HCF(208,78) = HCF(286,208) = HCF(494,286) = HCF(780,494) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 430 > 26, we apply the division lemma to 430 and 26, to get
430 = 26 x 16 + 14
Step 2: Since the reminder 26 ≠ 0, we apply division lemma to 14 and 26, to get
26 = 14 x 1 + 12
Step 3: We consider the new divisor 14 and the new remainder 12, and apply the division lemma to get
14 = 12 x 1 + 2
We consider the new divisor 12 and the new remainder 2, and apply the division lemma to get
12 = 2 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 26 and 430 is 2
Notice that 2 = HCF(12,2) = HCF(14,12) = HCF(26,14) = HCF(430,26) .
