Given numbers are 840, 284, 514, 672
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(840, 284) = 59640
GCD(840, 284) = ( 840 x 284 ) / 59640
= 840 / 284
= 840
Step2:
LCM(4, 514) = 1028
GCD(4, 514) = ( 4 x 514 ) / 1028
= 4 / 514
= 4
Step3:
LCM(2, 672) = 672
GCD(2, 672) = ( 2 x 672 ) / 672
= 2 / 672
= 2
So, Greatest Common Divisor of 840, 284, 514, 672 is 2
