Given numbers are 324, 390, 972, 943
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(324, 390) = 21060
GCD(324, 390) = ( 324 x 390 ) / 21060
= 324 / 390
= 324
Step2:
LCM(6, 972) = 972
GCD(6, 972) = ( 6 x 972 ) / 972
= 6 / 972
= 6
Step3:
LCM(6, 943) = 5658
GCD(6, 943) = ( 6 x 943 ) / 5658
= 6 / 943
= 6
So, Greatest Common Divisor of 324, 390, 972, 943 is 1
