HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 555, 940 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 555, 940 is 5 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 555, 940 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 555, 940 is 5.
HCF(555, 940) = 5
HCF of 555, 940 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 555, 940 is 5.
Highest Common Factor of 555,940 is 5
Step 1: Since 940 > 555, we apply the division lemma to 940 and 555, to get
940 = 555 x 1 + 385
Step 2: Since the reminder 555 ≠ 0, we apply division lemma to 385 and 555, to get
555 = 385 x 1 + 170
Step 3: We consider the new divisor 385 and the new remainder 170, and apply the division lemma to get
385 = 170 x 2 + 45
We consider the new divisor 170 and the new remainder 45,and apply the division lemma to get
170 = 45 x 3 + 35
We consider the new divisor 45 and the new remainder 35,and apply the division lemma to get
45 = 35 x 1 + 10
We consider the new divisor 35 and the new remainder 10,and apply the division lemma to get
35 = 10 x 3 + 5
We consider the new divisor 10 and the new remainder 5,and apply the division lemma to get
10 = 5 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 555 and 940 is 5
Notice that 5 = HCF(10,5) = HCF(35,10) = HCF(45,35) = HCF(170,45) = HCF(385,170) = HCF(555,385) = HCF(940,555) .
