HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 849, 354, 857, 503 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 849, 354, 857, 503 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 849, 354, 857, 503 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 849, 354, 857, 503 is 1.
HCF(849, 354, 857, 503) = 1
HCF of 849, 354, 857, 503 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 849, 354, 857, 503 is 1.
Highest Common Factor of 849,354,857,503 is 1
Step 1: Since 849 > 354, we apply the division lemma to 849 and 354, to get
849 = 354 x 2 + 141
Step 2: Since the reminder 354 ≠ 0, we apply division lemma to 141 and 354, to get
354 = 141 x 2 + 72
Step 3: We consider the new divisor 141 and the new remainder 72, and apply the division lemma to get
141 = 72 x 1 + 69
We consider the new divisor 72 and the new remainder 69,and apply the division lemma to get
72 = 69 x 1 + 3
We consider the new divisor 69 and the new remainder 3,and apply the division lemma to get
69 = 3 x 23 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 849 and 354 is 3
Notice that 3 = HCF(69,3) = HCF(72,69) = HCF(141,72) = HCF(354,141) = HCF(849,354) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 857 > 3, we apply the division lemma to 857 and 3, to get
857 = 3 x 285 + 2
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 2 and 3, to get
3 = 2 x 1 + 1
Step 3: 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 3 and 857 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(857,3) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 503 > 1, we apply the division lemma to 503 and 1, to get
503 = 1 x 503 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 503 is 1
Notice that 1 = HCF(503,1) .
