HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 918, 6840 i.e. 18 the largest integer that leaves a remainder zero for all numbers.
HCF of 918, 6840 is 18 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 918, 6840 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 918, 6840 is 18.
HCF(918, 6840) = 18
HCF of 918, 6840 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 918, 6840 is 18.
Highest Common Factor of 918,6840 is 18
Step 1: Since 6840 > 918, we apply the division lemma to 6840 and 918, to get
6840 = 918 x 7 + 414
Step 2: Since the reminder 918 ≠ 0, we apply division lemma to 414 and 918, to get
918 = 414 x 2 + 90
Step 3: We consider the new divisor 414 and the new remainder 90, and apply the division lemma to get
414 = 90 x 4 + 54
We consider the new divisor 90 and the new remainder 54,and apply the division lemma to get
90 = 54 x 1 + 36
We consider the new divisor 54 and the new remainder 36,and apply the division lemma to get
54 = 36 x 1 + 18
We consider the new divisor 36 and the new remainder 18,and apply the division lemma to get
36 = 18 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 18, the HCF of 918 and 6840 is 18
Notice that 18 = HCF(36,18) = HCF(54,36) = HCF(90,54) = HCF(414,90) = HCF(918,414) = HCF(6840,918) .
