Given numbers are 855, 757, 642, 233
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(855, 757) = 647235
GCD(855, 757) = ( 855 x 757 ) / 647235
= 855 / 757
= 855
Step2:
LCM(1, 642) = 642
GCD(1, 642) = ( 1 x 642 ) / 642
= 1 / 642
= 1
Step3:
LCM(1, 233) = 233
GCD(1, 233) = ( 1 x 233 ) / 233
= 1 / 233
= 1
So, Greatest Common Divisor of 855, 757, 642, 233 is 1
