HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 399, 912 i.e. 57 the largest integer that leaves a remainder zero for all numbers.
HCF of 399, 912 is 57 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 399, 912 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 399, 912 is 57.
HCF(399, 912) = 57
HCF of 399, 912 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 399, 912 is 57.
Highest Common Factor of 399,912 is 57
Step 1: Since 912 > 399, we apply the division lemma to 912 and 399, to get
912 = 399 x 2 + 114
Step 2: Since the reminder 399 ≠ 0, we apply division lemma to 114 and 399, to get
399 = 114 x 3 + 57
Step 3: We consider the new divisor 114 and the new remainder 57, and apply the division lemma to get
114 = 57 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 57, the HCF of 399 and 912 is 57
Notice that 57 = HCF(114,57) = HCF(399,114) = HCF(912,399) .
