Given numbers are 398, 782, 54, 553
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(398, 782) = 155618
GCD(398, 782) = ( 398 x 782 ) / 155618
= 398 / 782
= 398
Step2:
LCM(2, 54) = 54
GCD(2, 54) = ( 2 x 54 ) / 54
= 2 / 54
= 2
Step3:
LCM(2, 553) = 1106
GCD(2, 553) = ( 2 x 553 ) / 1106
= 2 / 553
= 2
So, Greatest Common Divisor of 398, 782, 54, 553 is 1
