Given numbers are 770, 945, 339, 441
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(770, 945) = 20790
GCD(770, 945) = ( 770 x 945 ) / 20790
= 770 / 945
= 770
Step2:
LCM(35, 339) = 11865
GCD(35, 339) = ( 35 x 339 ) / 11865
= 35 / 339
= 35
Step3:
LCM(1, 441) = 441
GCD(1, 441) = ( 1 x 441 ) / 441
= 1 / 441
= 1
So, Greatest Common Divisor of 770, 945, 339, 441 is 1
