Given numbers are 148, 552, 643, 130
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(148, 552) = 20424
GCD(148, 552) = ( 148 x 552 ) / 20424
= 148 / 552
= 148
Step2:
LCM(4, 643) = 2572
GCD(4, 643) = ( 4 x 643 ) / 2572
= 4 / 643
= 4
Step3:
LCM(1, 130) = 130
GCD(1, 130) = ( 1 x 130 ) / 130
= 1 / 130
= 1
So, Greatest Common Divisor of 148, 552, 643, 130 is 1
