Given numbers are 207, 645, 100, 439
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(207, 645) = 44505
GCD(207, 645) = ( 207 x 645 ) / 44505
= 207 / 645
= 207
Step2:
LCM(3, 100) = 300
GCD(3, 100) = ( 3 x 100 ) / 300
= 3 / 100
= 3
Step3:
LCM(1, 439) = 439
GCD(1, 439) = ( 1 x 439 ) / 439
= 1 / 439
= 1
So, Greatest Common Divisor of 207, 645, 100, 439 is 1
