HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 488, 619 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 488, 619 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 488, 619 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 488, 619 is 1.
HCF(488, 619) = 1
HCF of 488, 619 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 488, 619 is 1.
Highest Common Factor of 488,619 is 1
Step 1: Since 619 > 488, we apply the division lemma to 619 and 488, to get
619 = 488 x 1 + 131
Step 2: Since the reminder 488 ≠ 0, we apply division lemma to 131 and 488, to get
488 = 131 x 3 + 95
Step 3: We consider the new divisor 131 and the new remainder 95, and apply the division lemma to get
131 = 95 x 1 + 36
We consider the new divisor 95 and the new remainder 36,and apply the division lemma to get
95 = 36 x 2 + 23
We consider the new divisor 36 and the new remainder 23,and apply the division lemma to get
36 = 23 x 1 + 13
We consider the new divisor 23 and the new remainder 13,and apply the division lemma to get
23 = 13 x 1 + 10
We consider the new divisor 13 and the new remainder 10,and apply the division lemma to get
13 = 10 x 1 + 3
We consider the new divisor 10 and the new remainder 3,and apply the division lemma to get
10 = 3 x 3 + 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 488 and 619 is 1
Notice that 1 = HCF(3,1) = HCF(10,3) = HCF(13,10) = HCF(23,13) = HCF(36,23) = HCF(95,36) = HCF(131,95) = HCF(488,131) = HCF(619,488) .
