GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(165, 141) = 7755
GCD(165, 141) = ( 165 x 141 ) / 7755
= 165 / 141
= 165
Step2:
LCM(3, 651) = 651
GCD(3, 651) = ( 3 x 651 ) / 651
= 3 / 651
= 3
Step3:
LCM(3, 672) = 672
GCD(3, 672) = ( 3 x 672 ) / 672
= 3 / 672
= 3
So, Greatest Common Divisor of 165, 141, 651, 672 is 3
