HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 460, 730, 624 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 460, 730, 624 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 460, 730, 624 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 460, 730, 624 is 2.
HCF(460, 730, 624) = 2
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 460, 730, 624 is 2.
Step 1: Since 730 > 460, we apply the division lemma to 730 and 460, to get
730 = 460 x 1 + 270
Step 2: Since the reminder 460 ≠ 0, we apply division lemma to 270 and 460, to get
460 = 270 x 1 + 190
Step 3: We consider the new divisor 270 and the new remainder 190, and apply the division lemma to get
270 = 190 x 1 + 80
We consider the new divisor 190 and the new remainder 80,and apply the division lemma to get
190 = 80 x 2 + 30
We consider the new divisor 80 and the new remainder 30,and apply the division lemma to get
80 = 30 x 2 + 20
We consider the new divisor 30 and the new remainder 20,and apply the division lemma to get
30 = 20 x 1 + 10
We consider the new divisor 20 and the new remainder 10,and apply the division lemma to get
20 = 10 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 10, the HCF of 460 and 730 is 10
Notice that 10 = HCF(20,10) = HCF(30,20) = HCF(80,30) = HCF(190,80) = HCF(270,190) = HCF(460,270) = HCF(730,460) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 624 > 10, we apply the division lemma to 624 and 10, to get
624 = 10 x 62 + 4
Step 2: Since the reminder 10 ≠ 0, we apply division lemma to 4 and 10, to get
10 = 4 x 2 + 2
Step 3: We consider the new divisor 4 and the new remainder 2, and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 10 and 624 is 2
Notice that 2 = HCF(4,2) = HCF(10,4) = HCF(624,10) .
Here are some samples of HCF using Euclid's Algorithm calculations.
