Given numbers are 981, 671, 387, 506
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(981, 671) = 658251
GCD(981, 671) = ( 981 x 671 ) / 658251
= 981 / 671
= 981
Step2:
LCM(1, 387) = 387
GCD(1, 387) = ( 1 x 387 ) / 387
= 1 / 387
= 1
Step3:
LCM(1, 506) = 506
GCD(1, 506) = ( 1 x 506 ) / 506
= 1 / 506
= 1
So, Greatest Common Divisor of 981, 671, 387, 506 is 1
