Given numbers are 945, 938, 895, 143
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(945, 938) = 126630
GCD(945, 938) = ( 945 x 938 ) / 126630
= 945 / 938
= 945
Step2:
LCM(7, 895) = 6265
GCD(7, 895) = ( 7 x 895 ) / 6265
= 7 / 895
= 7
Step3:
LCM(1, 143) = 143
GCD(1, 143) = ( 1 x 143 ) / 143
= 1 / 143
= 1
So, Greatest Common Divisor of 945, 938, 895, 143 is 1
