Given numbers are 155, 396, 457, 635
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(155, 396) = 61380
GCD(155, 396) = ( 155 x 396 ) / 61380
= 155 / 396
= 155
Step2:
LCM(1, 457) = 457
GCD(1, 457) = ( 1 x 457 ) / 457
= 1 / 457
= 1
Step3:
LCM(1, 635) = 635
GCD(1, 635) = ( 1 x 635 ) / 635
= 1 / 635
= 1
So, Greatest Common Divisor of 155, 396, 457, 635 is 1
