Given numbers are 398, 805, 215, 141
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(398, 805) = 320390
GCD(398, 805) = ( 398 x 805 ) / 320390
= 398 / 805
= 398
Step2:
LCM(1, 215) = 215
GCD(1, 215) = ( 1 x 215 ) / 215
= 1 / 215
= 1
Step3:
LCM(1, 141) = 141
GCD(1, 141) = ( 1 x 141 ) / 141
= 1 / 141
= 1
So, Greatest Common Divisor of 398, 805, 215, 141 is 1
