Given numbers are 972, 840, 107, 945
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(972, 840) = 68040
GCD(972, 840) = ( 972 x 840 ) / 68040
= 972 / 840
= 972
Step2:
LCM(12, 107) = 1284
GCD(12, 107) = ( 12 x 107 ) / 1284
= 12 / 107
= 12
Step3:
LCM(1, 945) = 945
GCD(1, 945) = ( 1 x 945 ) / 945
= 1 / 945
= 1
So, Greatest Common Divisor of 972, 840, 107, 945 is 1
