HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 708, 390, 963 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 708, 390, 963 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 708, 390, 963 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 708, 390, 963 is 3.
HCF(708, 390, 963) = 3
HCF of 708, 390, 963 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 708, 390, 963 is 3.
Highest Common Factor of 708,390,963 is 3
Step 1: Since 708 > 390, we apply the division lemma to 708 and 390, to get
708 = 390 x 1 + 318
Step 2: Since the reminder 390 ≠ 0, we apply division lemma to 318 and 390, to get
390 = 318 x 1 + 72
Step 3: We consider the new divisor 318 and the new remainder 72, and apply the division lemma to get
318 = 72 x 4 + 30
We consider the new divisor 72 and the new remainder 30,and apply the division lemma to get
72 = 30 x 2 + 12
We consider the new divisor 30 and the new remainder 12,and apply the division lemma to get
30 = 12 x 2 + 6
We consider the new divisor 12 and the new remainder 6,and apply the division lemma to get
12 = 6 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 708 and 390 is 6
Notice that 6 = HCF(12,6) = HCF(30,12) = HCF(72,30) = HCF(318,72) = HCF(390,318) = HCF(708,390) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 963 > 6, we apply the division lemma to 963 and 6, to get
963 = 6 x 160 + 3
Step 2: Since the reminder 6 ≠ 0, we apply division lemma to 3 and 6, to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 6 and 963 is 3
Notice that 3 = HCF(6,3) = HCF(963,6) .
