Given numbers are 155, 772, 771, 412
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(155, 772) = 119660
GCD(155, 772) = ( 155 x 772 ) / 119660
= 155 / 772
= 155
Step2:
LCM(1, 771) = 771
GCD(1, 771) = ( 1 x 771 ) / 771
= 1 / 771
= 1
Step3:
LCM(1, 412) = 412
GCD(1, 412) = ( 1 x 412 ) / 412
= 1 / 412
= 1
So, Greatest Common Divisor of 155, 772, 771, 412 is 1
