HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 640, 808, 130 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 640, 808, 130 is 2 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 640, 808, 130 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 640, 808, 130 is 2.
HCF(640, 808, 130) = 2
HCF of 640, 808, 130 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 640, 808, 130 is 2.
Highest Common Factor of 640,808,130 is 2
Step 1: Since 808 > 640, we apply the division lemma to 808 and 640, to get
808 = 640 x 1 + 168
Step 2: Since the reminder 640 ≠ 0, we apply division lemma to 168 and 640, to get
640 = 168 x 3 + 136
Step 3: We consider the new divisor 168 and the new remainder 136, and apply the division lemma to get
168 = 136 x 1 + 32
We consider the new divisor 136 and the new remainder 32,and apply the division lemma to get
136 = 32 x 4 + 8
We consider the new divisor 32 and the new remainder 8,and apply the division lemma to get
32 = 8 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 8, the HCF of 640 and 808 is 8
Notice that 8 = HCF(32,8) = HCF(136,32) = HCF(168,136) = HCF(640,168) = HCF(808,640) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 130 > 8, we apply the division lemma to 130 and 8, to get
130 = 8 x 16 + 2
Step 2: Since the reminder 8 ≠ 0, we apply division lemma to 2 and 8, to get
8 = 2 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 8 and 130 is 2
Notice that 2 = HCF(8,2) = HCF(130,8) .
