HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 838, 144, 222, 547 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 838, 144, 222, 547 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 838, 144, 222, 547 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 838, 144, 222, 547 is 1.
HCF(838, 144, 222, 547) = 1
HCF of 838, 144, 222, 547 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 838, 144, 222, 547 is 1.
Highest Common Factor of 838,144,222,547 is 1
Step 1: Since 838 > 144, we apply the division lemma to 838 and 144, to get
838 = 144 x 5 + 118
Step 2: Since the reminder 144 ≠ 0, we apply division lemma to 118 and 144, to get
144 = 118 x 1 + 26
Step 3: We consider the new divisor 118 and the new remainder 26, and apply the division lemma to get
118 = 26 x 4 + 14
We consider the new divisor 26 and the new remainder 14,and apply the division lemma to get
26 = 14 x 1 + 12
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 838 and 144 is 2
Notice that 2 = HCF(12,2) = HCF(14,12) = HCF(26,14) = HCF(118,26) = HCF(144,118) = HCF(838,144) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 222 > 2, we apply the division lemma to 222 and 2, to get
222 = 2 x 111 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 222 is 2
Notice that 2 = HCF(222,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 547 > 2, we apply the division lemma to 547 and 2, to get
547 = 2 x 273 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 547 is 1
Notice that 1 = HCF(2,1) = HCF(547,2) .
