Given numbers are 153, 343, 618, 977

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

Apply this formula for all numbers.

Step1:

LCM(153, 343) = 52479

GCD(153, 343) = ( 153 x 343 ) / 52479

= 153 / 343

= 153

Step2:

LCM(1, 618) = 618

GCD(1, 618) = ( 1 x 618 ) / 618

= 1 / 618

= 1

Step3:

LCM(1, 977) = 977

GCD(1, 977) = ( 1 x 977 ) / 977

= 1 / 977

= 1

So, Greatest Common Divisor of 153, 343, 618, 977 is 1
