Given numbers are 155, 778, 963, 201

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(155, 778) = 120590

GCD(155, 778) = ( 155 x 778 ) / 120590

= 155 / 778

= 155

Step2:

LCM(1, 963) = 963

GCD(1, 963) = ( 1 x 963 ) / 963

= 1 / 963

= 1

Step3:

LCM(1, 201) = 201

GCD(1, 201) = ( 1 x 201 ) / 201

= 1 / 201

= 1

So, Greatest Common Divisor of 155, 778, 963, 201 is 1
