This is my method to find GCD of 2 big numbers A and B and expressing that gcd of the form mA + nBFirst, let us find the gcd. Let us call it as d1) Divide the bigger number by the smaller one.2) Divide the smaller number by the remainder u get in step 1.3) Divide the step 1 remainder by step 2, then each remainder by the next remainder and so on.4) Reach the step when u get no remainder at all. The divisor will be the LCM.Let me explain it with an example.Q. Find the gcd of 858 and 325 and express it in the form of m858 + n325.Solution :858 = 325*2 + 208325 = 208*1 + 117208 = 117*1 + 91117 = 91*1 + 2691 = 26*3 + 1326 = 13.2thr4, gcd 0f 858 and 325 is d = 13d = 13 = 91 - 26*3= 91 -3(117 - 91*1)= 91*4 - 117*3=4(208-117) - 117*3= 4*208 - 7*117= 4*208 - 7(325-208)=11*208 -7*325=11*(858-325*2) - 7*325=11*858 - 29*325thr4, d = 13 = m*858 + n*325 where m =11 and n = -29
Factors of 91: 1, 7, 13, 91Factors of 117: 1, 3, 9, 13, 39, 117GCF (91, 117) = 13
It is: 728
For 117, 91, 65, 21 the LCM is: 4,095
The GCF is 13.
26 + 91 = 117
The GCF is 13.
117/91(divide both sides by 13)9/7
The greatest common denominator (gcd) of 42 and 117 is 3. So 3 is the only factor of both.
To find the simplest form of 91 over 117, we need to find the greatest common factor (GCF) of the two numbers. The GCF of 91 and 117 is 13. Dividing both numbers by 13 gives us 7 over 9. Therefore, the simplest form of 91 over 117 is 7 over 9.
The answer is: 1
