HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 640, 17808 i.e. 16 the largest integer that leaves a remainder zero for all numbers.
HCF of 640, 17808 is 16 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, 17808 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, 17808 is 16.
HCF(640, 17808) = 16
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 640, 17808 is 16.
Step 1: Since 17808 > 640, we apply the division lemma to 17808 and 640, to get
17808 = 640 x 27 + 528
Step 2: Since the reminder 640 ≠ 0, we apply division lemma to 528 and 640, to get
640 = 528 x 1 + 112
Step 3: We consider the new divisor 528 and the new remainder 112, and apply the division lemma to get
528 = 112 x 4 + 80
We consider the new divisor 112 and the new remainder 80,and apply the division lemma to get
112 = 80 x 1 + 32
We consider the new divisor 80 and the new remainder 32,and apply the division lemma to get
80 = 32 x 2 + 16
We consider the new divisor 32 and the new remainder 16,and apply the division lemma to get
32 = 16 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 16, the HCF of 640 and 17808 is 16
Notice that 16 = HCF(32,16) = HCF(80,32) = HCF(112,80) = HCF(528,112) = HCF(640,528) = HCF(17808,640) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?
