Given numbers are 545, 620, 382, 213
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(545, 620) = 67580
GCD(545, 620) = ( 545 x 620 ) / 67580
= 545 / 620
= 545
Step2:
LCM(5, 382) = 1910
GCD(5, 382) = ( 5 x 382 ) / 1910
= 5 / 382
= 5
Step3:
LCM(1, 213) = 213
GCD(1, 213) = ( 1 x 213 ) / 213
= 1 / 213
= 1
So, Greatest Common Divisor of 545, 620, 382, 213 is 1
