HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 776, 162, 620 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 776, 162, 620 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 776, 162, 620 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 776, 162, 620 is 2.
HCF(776, 162, 620) = 2
HCF of 776, 162, 620 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 776, 162, 620 is 2.
Highest Common Factor of 776,162,620 is 2
Step 1: Since 776 > 162, we apply the division lemma to 776 and 162, to get
776 = 162 x 4 + 128
Step 2: Since the reminder 162 ≠ 0, we apply division lemma to 128 and 162, to get
162 = 128 x 1 + 34
Step 3: We consider the new divisor 128 and the new remainder 34, and apply the division lemma to get
128 = 34 x 3 + 26
We consider the new divisor 34 and the new remainder 26,and apply the division lemma to get
34 = 26 x 1 + 8
We consider the new divisor 26 and the new remainder 8,and apply the division lemma to get
26 = 8 x 3 + 2
We consider the new divisor 8 and the new remainder 2,and apply the division lemma to get
8 = 2 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 776 and 162 is 2
Notice that 2 = HCF(8,2) = HCF(26,8) = HCF(34,26) = HCF(128,34) = HCF(162,128) = HCF(776,162) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 620 > 2, we apply the division lemma to 620 and 2, to get
620 = 2 x 310 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 620 is 2
Notice that 2 = HCF(620,2) .
