Given numbers are 981, 284, 138, 841
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(981, 284) = 278604
GCD(981, 284) = ( 981 x 284 ) / 278604
= 981 / 284
= 981
Step2:
LCM(1, 138) = 138
GCD(1, 138) = ( 1 x 138 ) / 138
= 1 / 138
= 1
Step3:
LCM(1, 841) = 841
GCD(1, 841) = ( 1 x 841 ) / 841
= 1 / 841
= 1
So, Greatest Common Divisor of 981, 284, 138, 841 is 1
