Given numbers are 861, 588, 387, 554
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(861, 588) = 24108
GCD(861, 588) = ( 861 x 588 ) / 24108
= 861 / 588
= 861
Step2:
LCM(21, 387) = 2709
GCD(21, 387) = ( 21 x 387 ) / 2709
= 21 / 387
= 21
Step3:
LCM(3, 554) = 1662
GCD(3, 554) = ( 3 x 554 ) / 1662
= 3 / 554
= 3
So, Greatest Common Divisor of 861, 588, 387, 554 is 1
