HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 364, 840 i.e. 28 the largest integer that leaves a remainder zero for all numbers.
HCF of 364, 840 is 28 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 364, 840 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 364, 840 is 28.
HCF(364, 840) = 28
HCF of 364, 840 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 364, 840 is 28.
Highest Common Factor of 364,840 is 28
Step 1: Since 840 > 364, we apply the division lemma to 840 and 364, to get
840 = 364 x 2 + 112
Step 2: Since the reminder 364 ≠ 0, we apply division lemma to 112 and 364, to get
364 = 112 x 3 + 28
Step 3: We consider the new divisor 112 and the new remainder 28, and apply the division lemma to get
112 = 28 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 28, the HCF of 364 and 840 is 28
Notice that 28 = HCF(112,28) = HCF(364,112) = HCF(840,364) .
