HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 665, 999, 489, 141 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 665, 999, 489, 141 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 665, 999, 489, 141 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 665, 999, 489, 141 is 1.
HCF(665, 999, 489, 141) = 1
HCF of 665, 999, 489, 141 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 665, 999, 489, 141 is 1.
Highest Common Factor of 665,999,489,141 is 1
Step 1: Since 999 > 665, we apply the division lemma to 999 and 665, to get
999 = 665 x 1 + 334
Step 2: Since the reminder 665 ≠ 0, we apply division lemma to 334 and 665, to get
665 = 334 x 1 + 331
Step 3: We consider the new divisor 334 and the new remainder 331, and apply the division lemma to get
334 = 331 x 1 + 3
We consider the new divisor 331 and the new remainder 3,and apply the division lemma to get
331 = 3 x 110 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 665 and 999 is 1
Notice that 1 = HCF(3,1) = HCF(331,3) = HCF(334,331) = HCF(665,334) = HCF(999,665) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 489 > 1, we apply the division lemma to 489 and 1, to get
489 = 1 x 489 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 489 is 1
Notice that 1 = HCF(489,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 141 > 1, we apply the division lemma to 141 and 1, to get
141 = 1 x 141 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 141 is 1
Notice that 1 = HCF(141,1) .
