HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 796, 688, 780 i.e. 4 the largest integer that leaves a remainder zero for all numbers.
HCF of 796, 688, 780 is 4 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 796, 688, 780 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 796, 688, 780 is 4.
HCF(796, 688, 780) = 4
HCF of 796, 688, 780 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 796, 688, 780 is 4.
Highest Common Factor of 796,688,780 is 4
Step 1: Since 796 > 688, we apply the division lemma to 796 and 688, to get
796 = 688 x 1 + 108
Step 2: Since the reminder 688 ≠ 0, we apply division lemma to 108 and 688, to get
688 = 108 x 6 + 40
Step 3: We consider the new divisor 108 and the new remainder 40, and apply the division lemma to get
108 = 40 x 2 + 28
We consider the new divisor 40 and the new remainder 28,and apply the division lemma to get
40 = 28 x 1 + 12
We consider the new divisor 28 and the new remainder 12,and apply the division lemma to get
28 = 12 x 2 + 4
We consider the new divisor 12 and the new remainder 4,and apply the division lemma to get
12 = 4 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 796 and 688 is 4
Notice that 4 = HCF(12,4) = HCF(28,12) = HCF(40,28) = HCF(108,40) = HCF(688,108) = HCF(796,688) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 780 > 4, we apply the division lemma to 780 and 4, to get
780 = 4 x 195 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 4 and 780 is 4
Notice that 4 = HCF(780,4) .
