HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 872, 156 i.e. 4 the largest integer that leaves a remainder zero for all numbers.
HCF of 872, 156 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 872, 156 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 872, 156 is 4.
HCF(872, 156) = 4
HCF of 872, 156 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 872, 156 is 4.
Highest Common Factor of 872,156 is 4
Step 1: Since 872 > 156, we apply the division lemma to 872 and 156, to get
872 = 156 x 5 + 92
Step 2: Since the reminder 156 ≠ 0, we apply division lemma to 92 and 156, to get
156 = 92 x 1 + 64
Step 3: We consider the new divisor 92 and the new remainder 64, and apply the division lemma to get
92 = 64 x 1 + 28
We consider the new divisor 64 and the new remainder 28,and apply the division lemma to get
64 = 28 x 2 + 8
We consider the new divisor 28 and the new remainder 8,and apply the division lemma to get
28 = 8 x 3 + 4
We consider the new divisor 8 and the new remainder 4,and apply the division lemma to get
8 = 4 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 872 and 156 is 4
Notice that 4 = HCF(8,4) = HCF(28,8) = HCF(64,28) = HCF(92,64) = HCF(156,92) = HCF(872,156) .
