Given numbers are 840, 198, 156, 224
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(840, 198) = 27720
GCD(840, 198) = ( 840 x 198 ) / 27720
= 840 / 198
= 840
Step2:
LCM(6, 156) = 156
GCD(6, 156) = ( 6 x 156 ) / 156
= 6 / 156
= 6
Step3:
LCM(6, 224) = 672
GCD(6, 224) = ( 6 x 224 ) / 672
= 6 / 224
= 6
So, Greatest Common Divisor of 840, 198, 156, 224 is 2
