HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 604, 842, 156 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 604, 842, 156 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 604, 842, 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 604, 842, 156 is 2.
HCF(604, 842, 156) = 2
HCF of 604, 842, 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 604, 842, 156 is 2.
Highest Common Factor of 604,842,156 is 2
Step 1: Since 842 > 604, we apply the division lemma to 842 and 604, to get
842 = 604 x 1 + 238
Step 2: Since the reminder 604 ≠ 0, we apply division lemma to 238 and 604, to get
604 = 238 x 2 + 128
Step 3: We consider the new divisor 238 and the new remainder 128, and apply the division lemma to get
238 = 128 x 1 + 110
We consider the new divisor 128 and the new remainder 110,and apply the division lemma to get
128 = 110 x 1 + 18
We consider the new divisor 110 and the new remainder 18,and apply the division lemma to get
110 = 18 x 6 + 2
We consider the new divisor 18 and the new remainder 2,and apply the division lemma to get
18 = 2 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 604 and 842 is 2
Notice that 2 = HCF(18,2) = HCF(110,18) = HCF(128,110) = HCF(238,128) = HCF(604,238) = HCF(842,604) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 156 > 2, we apply the division lemma to 156 and 2, to get
156 = 2 x 78 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 156 is 2
Notice that 2 = HCF(156,2) .
