HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 147, 210, 229, 246 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 147, 210, 229, 246 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 147, 210, 229, 246 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 147, 210, 229, 246 is 1.
HCF(147, 210, 229, 246) = 1
HCF of 147, 210, 229, 246 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 147, 210, 229, 246 is 1.
Highest Common Factor of 147,210,229,246 is 1
Step 1: Since 210 > 147, we apply the division lemma to 210 and 147, to get
210 = 147 x 1 + 63
Step 2: Since the reminder 147 ≠ 0, we apply division lemma to 63 and 147, to get
147 = 63 x 2 + 21
Step 3: We consider the new divisor 63 and the new remainder 21, and apply the division lemma to get
63 = 21 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 21, the HCF of 147 and 210 is 21
Notice that 21 = HCF(63,21) = HCF(147,63) = HCF(210,147) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 229 > 21, we apply the division lemma to 229 and 21, to get
229 = 21 x 10 + 19
Step 2: Since the reminder 21 ≠ 0, we apply division lemma to 19 and 21, to get
21 = 19 x 1 + 2
Step 3: We consider the new divisor 19 and the new remainder 2, and apply the division lemma to get
19 = 2 x 9 + 1
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 21 and 229 is 1
Notice that 1 = HCF(2,1) = HCF(19,2) = HCF(21,19) = HCF(229,21) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 246 > 1, we apply the division lemma to 246 and 1, to get
246 = 1 x 246 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 246 is 1
Notice that 1 = HCF(246,1) .
