HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 708, 782 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 708, 782 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 708, 782 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, 782 is 2.
HCF(708, 782) = 2
HCF of 708, 782 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, 782 is 2.
Highest Common Factor of 708,782 is 2
Step 1: Since 782 > 708, we apply the division lemma to 782 and 708, to get
782 = 708 x 1 + 74
Step 2: Since the reminder 708 ≠ 0, we apply division lemma to 74 and 708, to get
708 = 74 x 9 + 42
Step 3: We consider the new divisor 74 and the new remainder 42, and apply the division lemma to get
74 = 42 x 1 + 32
We consider the new divisor 42 and the new remainder 32,and apply the division lemma to get
42 = 32 x 1 + 10
We consider the new divisor 32 and the new remainder 10,and apply the division lemma to get
32 = 10 x 3 + 2
We consider the new divisor 10 and the new remainder 2,and apply the division lemma to get
10 = 2 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 708 and 782 is 2
Notice that 2 = HCF(10,2) = HCF(32,10) = HCF(42,32) = HCF(74,42) = HCF(708,74) = HCF(782,708) .
