HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 308, 120 i.e. 4 the largest integer that leaves a remainder zero for all numbers.
HCF of 308, 120 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 308, 120 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 308, 120 is 4.
HCF(308, 120) = 4
HCF of 308, 120 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 308, 120 is 4.
Highest Common Factor of 308,120 is 4
Step 1: Since 308 > 120, we apply the division lemma to 308 and 120, to get
308 = 120 x 2 + 68
Step 2: Since the reminder 120 ≠ 0, we apply division lemma to 68 and 120, to get
120 = 68 x 1 + 52
Step 3: We consider the new divisor 68 and the new remainder 52, and apply the division lemma to get
68 = 52 x 1 + 16
We consider the new divisor 52 and the new remainder 16,and apply the division lemma to get
52 = 16 x 3 + 4
We consider the new divisor 16 and the new remainder 4,and apply the division lemma to get
16 = 4 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 308 and 120 is 4
Notice that 4 = HCF(16,4) = HCF(52,16) = HCF(68,52) = HCF(120,68) = HCF(308,120) .
