HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 857, 498, 224 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 857, 498, 224 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 857, 498, 224 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 857, 498, 224 is 1.
HCF(857, 498, 224) = 1
HCF of 857, 498, 224 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 857, 498, 224 is 1.
Highest Common Factor of 857,498,224 is 1
Step 1: Since 857 > 498, we apply the division lemma to 857 and 498, to get
857 = 498 x 1 + 359
Step 2: Since the reminder 498 ≠ 0, we apply division lemma to 359 and 498, to get
498 = 359 x 1 + 139
Step 3: We consider the new divisor 359 and the new remainder 139, and apply the division lemma to get
359 = 139 x 2 + 81
We consider the new divisor 139 and the new remainder 81,and apply the division lemma to get
139 = 81 x 1 + 58
We consider the new divisor 81 and the new remainder 58,and apply the division lemma to get
81 = 58 x 1 + 23
We consider the new divisor 58 and the new remainder 23,and apply the division lemma to get
58 = 23 x 2 + 12
We consider the new divisor 23 and the new remainder 12,and apply the division lemma to get
23 = 12 x 1 + 11
We consider the new divisor 12 and the new remainder 11,and apply the division lemma to get
12 = 11 x 1 + 1
We consider the new divisor 11 and the new remainder 1,and apply the division lemma to get
11 = 1 x 11 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 857 and 498 is 1
Notice that 1 = HCF(11,1) = HCF(12,11) = HCF(23,12) = HCF(58,23) = HCF(81,58) = HCF(139,81) = HCF(359,139) = HCF(498,359) = HCF(857,498) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 224 > 1, we apply the division lemma to 224 and 1, to get
224 = 1 x 224 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 224 is 1
Notice that 1 = HCF(224,1) .
