Given numbers are 620, 208, 661, 444
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(620, 208) = 32240
GCD(620, 208) = ( 620 x 208 ) / 32240
= 620 / 208
= 620
Step2:
LCM(4, 661) = 2644
GCD(4, 661) = ( 4 x 661 ) / 2644
= 4 / 661
= 4
Step3:
LCM(1, 444) = 444
GCD(1, 444) = ( 1 x 444 ) / 444
= 1 / 444
= 1
So, Greatest Common Divisor of 620, 208, 661, 444 is 1
