Given numbers are 470, 655, 124, 156
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(470, 655) = 61570
GCD(470, 655) = ( 470 x 655 ) / 61570
= 470 / 655
= 470
Step2:
LCM(5, 124) = 620
GCD(5, 124) = ( 5 x 124 ) / 620
= 5 / 124
= 5
Step3:
LCM(1, 156) = 156
GCD(1, 156) = ( 1 x 156 ) / 156
= 1 / 156
= 1
So, Greatest Common Divisor of 470, 655, 124, 156 is 1
