HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 420, 276, 123, 833 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 420, 276, 123, 833 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 420, 276, 123, 833 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 420, 276, 123, 833 is 1.
HCF(420, 276, 123, 833) = 1
HCF of 420, 276, 123, 833 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 420, 276, 123, 833 is 1.
Highest Common Factor of 420,276,123,833 is 1
Step 1: Since 420 > 276, we apply the division lemma to 420 and 276, to get
420 = 276 x 1 + 144
Step 2: Since the reminder 276 ≠ 0, we apply division lemma to 144 and 276, to get
276 = 144 x 1 + 132
Step 3: We consider the new divisor 144 and the new remainder 132, and apply the division lemma to get
144 = 132 x 1 + 12
We consider the new divisor 132 and the new remainder 12, and apply the division lemma to get
132 = 12 x 11 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 12, the HCF of 420 and 276 is 12
Notice that 12 = HCF(132,12) = HCF(144,132) = HCF(276,144) = HCF(420,276) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 123 > 12, we apply the division lemma to 123 and 12, to get
123 = 12 x 10 + 3
Step 2: Since the reminder 12 ≠ 0, we apply division lemma to 3 and 12, to get
12 = 3 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 12 and 123 is 3
Notice that 3 = HCF(12,3) = HCF(123,12) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 833 > 3, we apply the division lemma to 833 and 3, to get
833 = 3 x 277 + 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 833 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(833,3) .
