HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 494, 851, 786, 288 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 494, 851, 786, 288 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 494, 851, 786, 288 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, 851, 786, 288 is 1.
HCF(494, 851, 786, 288) = 1
HCF of 494, 851, 786, 288 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, 851, 786, 288 is 1.
Highest Common Factor of 494,851,786,288 is 1
Step 1: Since 851 > 494, we apply the division lemma to 851 and 494, to get
851 = 494 x 1 + 357
Step 2: Since the reminder 494 ≠ 0, we apply division lemma to 357 and 494, to get
494 = 357 x 1 + 137
Step 3: We consider the new divisor 357 and the new remainder 137, and apply the division lemma to get
357 = 137 x 2 + 83
We consider the new divisor 137 and the new remainder 83,and apply the division lemma to get
137 = 83 x 1 + 54
We consider the new divisor 83 and the new remainder 54,and apply the division lemma to get
83 = 54 x 1 + 29
We consider the new divisor 54 and the new remainder 29,and apply the division lemma to get
54 = 29 x 1 + 25
We consider the new divisor 29 and the new remainder 25,and apply the division lemma to get
29 = 25 x 1 + 4
We consider the new divisor 25 and the new remainder 4,and apply the division lemma to get
25 = 4 x 6 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 494 and 851 is 1
Notice that 1 = HCF(4,1) = HCF(25,4) = HCF(29,25) = HCF(54,29) = HCF(83,54) = HCF(137,83) = HCF(357,137) = HCF(494,357) = HCF(851,494) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 786 > 1, we apply the division lemma to 786 and 1, to get
786 = 1 x 786 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 786 is 1
Notice that 1 = HCF(786,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 288 > 1, we apply the division lemma to 288 and 1, to get
288 = 1 x 288 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 288 is 1
Notice that 1 = HCF(288,1) .
