HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 513, 792, 660 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 513, 792, 660 is 3 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 513, 792, 660 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 513, 792, 660 is 3.
HCF(513, 792, 660) = 3
HCF of 513, 792, 660 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 513, 792, 660 is 3.
Highest Common Factor of 513,792,660 is 3
Step 1: Since 792 > 513, we apply the division lemma to 792 and 513, to get
792 = 513 x 1 + 279
Step 2: Since the reminder 513 ≠ 0, we apply division lemma to 279 and 513, to get
513 = 279 x 1 + 234
Step 3: We consider the new divisor 279 and the new remainder 234, and apply the division lemma to get
279 = 234 x 1 + 45
We consider the new divisor 234 and the new remainder 45,and apply the division lemma to get
234 = 45 x 5 + 9
We consider the new divisor 45 and the new remainder 9,and apply the division lemma to get
45 = 9 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 9, the HCF of 513 and 792 is 9
Notice that 9 = HCF(45,9) = HCF(234,45) = HCF(279,234) = HCF(513,279) = HCF(792,513) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 660 > 9, we apply the division lemma to 660 and 9, to get
660 = 9 x 73 + 3
Step 2: Since the reminder 9 ≠ 0, we apply division lemma to 3 and 9, to get
9 = 3 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 9 and 660 is 3
Notice that 3 = HCF(9,3) = HCF(660,9) .
