Given numbers are 145, 747, 686, 375
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(145, 747) = 108315
GCD(145, 747) = ( 145 x 747 ) / 108315
= 145 / 747
= 145
Step2:
LCM(1, 686) = 686
GCD(1, 686) = ( 1 x 686 ) / 686
= 1 / 686
= 1
Step3:
LCM(1, 375) = 375
GCD(1, 375) = ( 1 x 375 ) / 375
= 1 / 375
= 1
So, Greatest Common Divisor of 145, 747, 686, 375 is 1
