GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(864, 672) = 6048
GCD(864, 672) = ( 864 x 672 ) / 6048
= 864 / 672
= 864
Step2:
LCM(96, 648) = 2592
GCD(96, 648) = ( 96 x 648 ) / 2592
= 96 / 648
= 96
Step3:
LCM(24, 660) = 1320
GCD(24, 660) = ( 24 x 660 ) / 1320
= 24 / 660
= 24
So, Greatest Common Divisor of 864, 672, 648, 660 is 12
