HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 284, 789, 468, 421 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 284, 789, 468, 421 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 284, 789, 468, 421 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 284, 789, 468, 421 is 1.
HCF(284, 789, 468, 421) = 1
HCF of 284, 789, 468, 421 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 284, 789, 468, 421 is 1.
Highest Common Factor of 284,789,468,421 is 1
Step 1: Since 789 > 284, we apply the division lemma to 789 and 284, to get
789 = 284 x 2 + 221
Step 2: Since the reminder 284 ≠ 0, we apply division lemma to 221 and 284, to get
284 = 221 x 1 + 63
Step 3: We consider the new divisor 221 and the new remainder 63, and apply the division lemma to get
221 = 63 x 3 + 32
We consider the new divisor 63 and the new remainder 32,and apply the division lemma to get
63 = 32 x 1 + 31
We consider the new divisor 32 and the new remainder 31,and apply the division lemma to get
32 = 31 x 1 + 1
We consider the new divisor 31 and the new remainder 1,and apply the division lemma to get
31 = 1 x 31 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 284 and 789 is 1
Notice that 1 = HCF(31,1) = HCF(32,31) = HCF(63,32) = HCF(221,63) = HCF(284,221) = HCF(789,284) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 468 > 1, we apply the division lemma to 468 and 1, to get
468 = 1 x 468 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 468 is 1
Notice that 1 = HCF(468,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 421 > 1, we apply the division lemma to 421 and 1, to get
421 = 1 x 421 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 421 is 1
Notice that 1 = HCF(421,1) .
