Given numbers are 284, 142, 653, 391
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(284, 142) = 284
GCD(284, 142) = ( 284 x 142 ) / 284
= 284 / 142
= 284
Step2:
LCM(142, 653) = 92726
GCD(142, 653) = ( 142 x 653 ) / 92726
= 142 / 653
= 142
Step3:
LCM(1, 391) = 391
GCD(1, 391) = ( 1 x 391 ) / 391
= 1 / 391
= 1
So, Greatest Common Divisor of 284, 142, 653, 391 is 1
