HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 851, 80438 i.e. 37 the largest integer that leaves a remainder zero for all numbers.
HCF of 851, 80438 is 37 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 851, 80438 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 851, 80438 is 37.
HCF(851, 80438) = 37
HCF of 851, 80438 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 851, 80438 is 37.
Highest Common Factor of 851,80438 is 37
Step 1: Since 80438 > 851, we apply the division lemma to 80438 and 851, to get
80438 = 851 x 94 + 444
Step 2: Since the reminder 851 ≠ 0, we apply division lemma to 444 and 851, to get
851 = 444 x 1 + 407
Step 3: We consider the new divisor 444 and the new remainder 407, and apply the division lemma to get
444 = 407 x 1 + 37
We consider the new divisor 407 and the new remainder 37, and apply the division lemma to get
407 = 37 x 11 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 37, the HCF of 851 and 80438 is 37
Notice that 37 = HCF(407,37) = HCF(444,407) = HCF(851,444) = HCF(80438,851) .
