GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(149, 770) = 114730
GCD(149, 770) = ( 149 x 770 ) / 114730
= 149 / 770
= 149
Step2:
LCM(1, 643) = 643
GCD(1, 643) = ( 1 x 643 ) / 643
= 1 / 643
= 1
Step3:
LCM(1, 945) = 945
GCD(1, 945) = ( 1 x 945 ) / 945
= 1 / 945
= 1
So, Greatest Common Divisor of 149, 770, 643, 945 is 1
