Given numbers are 645, 955, 540, 751
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(645, 955) = 123195
GCD(645, 955) = ( 645 x 955 ) / 123195
= 645 / 955
= 645
Step2:
LCM(5, 540) = 540
GCD(5, 540) = ( 5 x 540 ) / 540
= 5 / 540
= 5
Step3:
LCM(5, 751) = 3755
GCD(5, 751) = ( 5 x 751 ) / 3755
= 5 / 751
= 5
So, Greatest Common Divisor of 645, 955, 540, 751 is 1
