HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 249, 1942 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 249, 1942 is 1 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 249, 1942 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 249, 1942 is 1.
HCF(249, 1942) = 1
HCF of 249, 1942 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 249, 1942 is 1.
Highest Common Factor of 249,1942 is 1
Step 1: Since 1942 > 249, we apply the division lemma to 1942 and 249, to get
1942 = 249 x 7 + 199
Step 2: Since the reminder 249 ≠ 0, we apply division lemma to 199 and 249, to get
249 = 199 x 1 + 50
Step 3: We consider the new divisor 199 and the new remainder 50, and apply the division lemma to get
199 = 50 x 3 + 49
We consider the new divisor 50 and the new remainder 49,and apply the division lemma to get
50 = 49 x 1 + 1
We consider the new divisor 49 and the new remainder 1,and apply the division lemma to get
49 = 1 x 49 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 249 and 1942 is 1
Notice that 1 = HCF(49,1) = HCF(50,49) = HCF(199,50) = HCF(249,199) = HCF(1942,249) .
