Given numbers are 945, 387, 210, 545
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(945, 387) = 40635
GCD(945, 387) = ( 945 x 387 ) / 40635
= 945 / 387
= 945
Step2:
LCM(9, 210) = 630
GCD(9, 210) = ( 9 x 210 ) / 630
= 9 / 210
= 9
Step3:
LCM(3, 545) = 1635
GCD(3, 545) = ( 3 x 545 ) / 1635
= 3 / 545
= 3
So, Greatest Common Divisor of 945, 387, 210, 545 is 1
