Given numbers are 641, 145, 763, 111

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

Apply this formula for all numbers.

Step1:

LCM(641, 145) = 92945

GCD(641, 145) = ( 641 x 145 ) / 92945

= 641 / 145

= 641

Step2:

LCM(1, 763) = 763

GCD(1, 763) = ( 1 x 763 ) / 763

= 1 / 763

= 1

Step3:

LCM(1, 111) = 111

GCD(1, 111) = ( 1 x 111 ) / 111

= 1 / 111

= 1

So, Greatest Common Divisor of 641, 145, 763, 111 is 1
