HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 938, 840 i.e. 14 the largest integer that leaves a remainder zero for all numbers.
HCF of 938, 840 is 14 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 938, 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 938, 840 is 14.
HCF(938, 840) = 14
HCF of 938, 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 938, 840 is 14.
Highest Common Factor of 938,840 is 14
Step 1: Since 938 > 840, we apply the division lemma to 938 and 840, to get
938 = 840 x 1 + 98
Step 2: Since the reminder 840 ≠ 0, we apply division lemma to 98 and 840, to get
840 = 98 x 8 + 56
Step 3: We consider the new divisor 98 and the new remainder 56, and apply the division lemma to get
98 = 56 x 1 + 42
We consider the new divisor 56 and the new remainder 42,and apply the division lemma to get
56 = 42 x 1 + 14
We consider the new divisor 42 and the new remainder 14,and apply the division lemma to get
42 = 14 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 14, the HCF of 938 and 840 is 14
Notice that 14 = HCF(42,14) = HCF(56,42) = HCF(98,56) = HCF(840,98) = HCF(938,840) .
