Given numbers are 100, 985, 698, 394
The list of prime factors of all numbers are
Prime factors of 100 are 2 x 2 x 5 x 5
Prime factors of 985 are 5 x 197
Prime factors of 698 are 2 x 349
Prime factors of 394 are 2 x 197
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 100, 985, 698, 394
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(100, 985) = 19700
GCD(100, 985) = ( 100 x 985 ) / 19700
= 100 / 985
= 100
Step2:
LCM(5, 698) = 3490
GCD(5, 698) = ( 5 x 698 ) / 3490
= 5 / 698
= 5
Step3:
LCM(1, 394) = 394
GCD(1, 394) = ( 1 x 394 ) / 394
= 1 / 394
= 1
So, Greatest Common Divisor of 100, 985, 698, 394 is 1
