Given numbers are 662, 487, 620, 258
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(662, 487) = 322394
GCD(662, 487) = ( 662 x 487 ) / 322394
= 662 / 487
= 662
Step2:
LCM(1, 620) = 620
GCD(1, 620) = ( 1 x 620 ) / 620
= 1 / 620
= 1
Step3:
LCM(1, 258) = 258
GCD(1, 258) = ( 1 x 258 ) / 258
= 1 / 258
= 1
So, Greatest Common Divisor of 662, 487, 620, 258 is 1
