Given numbers are 770, 987, 715, 132
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(770, 987) = 108570
GCD(770, 987) = ( 770 x 987 ) / 108570
= 770 / 987
= 770
Step2:
LCM(7, 715) = 5005
GCD(7, 715) = ( 7 x 715 ) / 5005
= 7 / 715
= 7
Step3:
LCM(1, 132) = 132
GCD(1, 132) = ( 1 x 132 ) / 132
= 1 / 132
= 1
So, Greatest Common Divisor of 770, 987, 715, 132 is 1
