Given numbers are 672, 890, 847, 407
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(672, 890) = 299040
GCD(672, 890) = ( 672 x 890 ) / 299040
= 672 / 890
= 672
Step2:
LCM(2, 847) = 1694
GCD(2, 847) = ( 2 x 847 ) / 1694
= 2 / 847
= 2
Step3:
LCM(1, 407) = 407
GCD(1, 407) = ( 1 x 407 ) / 407
= 1 / 407
= 1
So, Greatest Common Divisor of 672, 890, 847, 407 is 1
